1) The rate constant for forward reaction and backward reaction of hydrolysics of ester are 1.1×10−2 and 1.5×10−3 per minute respectively . Equilibrium constant for the reaction is CH3COOC2H5+H2O⇌CH3COOH+C2H5OH A) 33.7 B) 7.33 C) 5.33 D) 33.3 Answer: Option BExplanation:given kf=1.1×10−2,kb=1.5×10−3 kc=kfkb=1.1×10−21.5×10−3=7.33
