NEET Chemistry Chemical Kinetics Questions Solved

NEET - 2009

Half-life period of a first order reaction is 1386s. The specific rate constant of the reaction is

(a) 5.0 x 10-3s-1

(b) 0.5 x 10-2s-1

(c) 0.5 x 10-3s-1

(d) 5.0 x 10-2s-1

Specific rate constant, K = 0.693/t1/2 = 0.693/1386

=  5.0 x 10-3s-1
