The standard heat of reaction for the production of formaldehyde in the reaction, 2 CH3OH (l) + O2 (g) -> 2 HCHO (g) + 2 H2O (l), is -326.2 kJ/mol.a. Is the reaction exothermic or endothermic? Would you heat or cool the reactor to keep the temperature constant?b. Explain physically why heat is released or absorbed when a reaction occurs.c. If the temperature and pressure are keep at standard (25°C, 1 atm), what is the rate of heating/cooling required in kcal/hr if 1000 kg/hr of formaldehyde is formed?

Question
The standard heat of reaction for the production of formaldehyde in the reaction, 2 CH3OH (l) + O2 (g) -> 2 HCHO (g) + 2 H2O (l), is -326.2 kJ/mol.
a. Is the reaction exothermic or endothermic? Would you heat or cool the reactor to keep the temperature constant?
b. Explain physically why heat is released or absorbed when a reaction occurs.
c. If the temperature and pressure are keep at standard (25°C, 1 atm), what is the rate of heating/cooling required in kcal/hr if 1000 kg/hr of formaldehyde is formed?
