48. The rate constant of a first order reaction is10-3 sec-1. At a reactant concentration of0.02 M, the rate of reaction would be-(1) 8 x 10s M sec (2) 4 x 10 M sec(3) 2 x 101 M sec (4) 4 x 101 M sec

Answer»

The rate of reaction is K*[A]

here k = 4*10-³ and [A] = 0.02 = 2*10-² so, rate of reaction is 8*10^(-5)M/s

option A.
