Question

CHEMICAL KINETICS
For a given reaction, energy of activation for forward reaction (Ef) is 80kj/mol.
AH = – 40kJ/ molfor the reaction. A catalyst lowers Efto 20 kJ/ mol. The ratio of energy of
activation for reverse reaction before and after addition of catalyst is :
(1) 1.0
(2) 0.5
(3) 1.2
(4)2.0
​
