NEET Chemistry Surface Chemistry Questions Solved


At 400K energy of activation of a reaction is decreased by 0.8 kcal in presence of catalyst. Hence rate will be

(A) Increased by 2.71 times

(B) Increased by 1.18 times

(C) Decreased by 2.72 times

(D) Increased by 6.26 times

A.  K1no catalyst=Ae-Ea/RT         K2catalyst=Ae-Ea-0.8/RT         K2K1=e0.8/RT=e0.8/0.002×400=2.72
