2. In a chemical reaction with activation energy Ea = 20 kJ/mol, (a) how many folds the rate constant is increased when the temperature increases from 300 K to 1000 K? That is, the ratio of k(1000K)=k(300K). (b) In the presence of a catalyst , the activation energy is brought down to 10 kJ/mol, how many folds the rate constant is increased at the same temperature 300K?
