NEET Chemistry Chemical Kinetics Questions Solved

If ‘a’ is the initial concentration of a substance which reacts according to zero order kinetic and k is rate constant, the time for the reaction to go to completion is-

(A) a/k                                                       

(B) 2/ka

(C) k/a                                                       

(D) Infinite

(A) For order reaction At=A0-kt

    For completion of reaction

At=0 and t=A0k& A0=a ; t=ak
