The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the concentration of substances used in the reaction. There are multiple formulas for finding reaction rates depending on the different substances used and the complexity of these reactions. As more components are added to the reaction, more complicated formulas are used to find the rates at which they occur. For example, in certain reactions, if concentrations of the reactants change, so do the resulting products. Stoichiometry is also used in finding reaction rates. As in reaction rates, the relationship of reactant and product amounts is a determining factor in the measurement. When other substances are added in a reaction formula that are not part of the reaction being measured but are still needed for the reaction to take place, the new formula for finding reaction rate must include how much substance is produced or consumed during the reaction, Complex reactions are calculated in a slightly different way as compared to elementary type reactions. At first, a reaction is experimentally tested, and a rate law is determined. Then, the stoichiometry is done and compared to find the correct formula for finding the reaction rate. In open systems, the amount of substance that can change the volume must be accounted for. As the amounts of substances flowing in and out of the …show more content…

Ligand Field Theory (LFT): LFT is a more comprehensive and sophisticated theory is now evolved from the combination of CFT and MOT. Cotton defined LFT as the theory of the origin and the consequence of the splitting of the inner orbitals of transition metal ions and their chemical environment. The CFT assumes that the orbitals of the ligand atom do not overlap with the orbitals of the central metal ion under consideration. However, sufficient experimental evidence shows that there always some overlapping between ligand and metal orbitals. It has been proved that the metal complexes have some degree of covalency in them as against what was thought by the CFT modelists.…

The following figures illustrate the energy profile diagram of SN1 and SN2 reactions. Difference Between SN1 and SN2 Reactions Rate Law SN1 Reaction: SN1 Reaction is unimolecular and a first order reaction. So substrate affects the reaction rate. SN2 Reaction: SN2 Reaction is bimolecular or a second order reaction. So, both substrate and nucleophile affect the reaction rate.…

The kinetic factors which controls the rate of reaction are, the concentration of reactants, the reaction mechanism, the energy barrier required to be overcome i.e. its activation energy, and temperature Rate of a reaction The rate of a chemical reaction, is change in concentration in unit time. Hence the rate of a reaction has units of concentration per unit time i.e. mol dm-3 s-1. For gaseous reactions, alternative units of concentration are often used, likes units of pressure – Torr, mbar or Pa).…

Le Chatelier’s Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of the equilibrium moves to counteract the change. At equilibrium point, a substantial amount of ester, alcohol, water and carboxylic acid was present in the round bottom flask. So to ensure a reasonable yield of the ester, an excess of the alcohols (2-pentanol, 2-butanol and benzyl alcohol) was used to drive the reaction faster. Acetic acid was used as the limiting reagent. The alcohol was used in excess.…

In the experiment the results showed how the reaction time of a reaction can be affected by different variables like temperature and quantity. The hypothesis of the experiment was that Sodium thiosulfate would be the agent that affects the time of the reaction. This was proven partially since the data from figure 3 and figure 1 shows that the higher concentration of Sodium thiosulfate causes the solution to take longer to occur therefore supporting the hypothesis. Data from figure 3 also shows that increasing KI in the solution causes the reaction time to occur faster. The data from figure 2 show that temperature also factors into the time it takes for the color change to occur.…

In this compound the two ions that make this up are: H+ and Cl-. So when these ions dissociate in a solution, the max ion concentration that the solution can reach is 2.0 M; whereas in a 1.0 M CaCl2 solution the ions include Ca2+ and Cl-. Therefore the ion concentration here is 3.0 M. This should have an effect on the conductivity as the concentration of ions will be different. In part B slope will be used to analyze the effect that concentration and charge have on the conductivity of a solution. Slope of a line determines the rate of change, and therefore the magnitude of the effect of these two variables.…

Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. Chemical reactions vary greatly in the speed at which they occur. Some are essentially instantaneous, while others may take a very long time to reach equilibrium. The reaction is presented by The time in the reaction when the mixture remains colourless is the clock period. This will depend upon the initial concentrations of the sodium bisulphite ions (NaHSO3) and the potassium iodate ions (KIO3).…
