NEET Chemistry Chemical Kinetics Questions Solved


K for a zero order reaction is 2 x10-2 mol L-1 sec-1. If the concentration of the reactant after 25 sec is 0.5 M, the initial concentration must have been:

(a) 0.5 M

(b) 1.25 M

(c) 12.5M

(d) 1.0 M

(d) For zero order [A]t = [A]0 - kt

     0.5 = [A]0 - 2x10-2x25

     [A]0 = 1.0M
