1)

The rate constant for forward reaction and backward reaction of hydrolysics of ester are 1.1×102 and 1.5×103 per minute respectively . Equilibrium constant for the reaction is 

CH3COOC2H5+H2OCH3COOH+C2H5OH


A) 33.7

B) 7.33

C) 5.33

D) 33.3

Answer:

Option B

Explanation:

given kf=1.1×102,kb=1.5×103

kc=kfkb=1.1×1021.5×103=7.33
