Content: As the concentration of NaHCO3 increases the rate of the reaction will also increase at a proportional rate. Introduction
Every species on earth needs some kind of energy source in order to survive. In animal cells, the mitochondria produce ATP from cellular respiration. However, the plant cells have a different type of center that produces energy-chloroplasts. Plants go through the process of photosynthesis. The main process of photosynthesis is the absorption of light by chlorophyll, found in leaves and the immersion of carbon dioxide from the environment, and together they produce oxygen and sugar (energy). The equation below represents the photosynthesis reaction: The purpose of this experiment is to test whether factors such as light intensity and level of Carbon dioxide, will affect the rate of photosynthesis, which are the two most important variables in the photosynthesis process. This was demonstrated by Robert Hill in 1938, known as “The Hill Reaction”. Robert Hill and his associates at the University of Illinois found that the photosynthetic rate varies with light intensity, and as the light intensity increases, the reaction rate also increases up to a certain point.
