Question

True or False

Identify which of the following statements are incorrect. If the statement is incorrect, rewrite it to be correct. Reactions are faster at a higher temperature because activation energies are lower. Rates increase with increasing concentration of reactants because there are more collisions between reactant molecules. At higher temperatures, a larger fraction of molecules have enough energy to get over the activation energy barrier. Catalyzed and uncatalyzed reactions have identical mechansims.

Explanation / Answer

a) Incorrect ( for exothermic reactions its not true.)
b) correct
c) Correct
d) Incorrect ( catalyzed reaction will have lower activation energy)
