NEET Chemistry Chemical Kinetics Questions Solved

BOARD

The rate constant for a reaction of zero orde in A is 0.0030 mol L-1 s-1.How long will it take for the initial concentration of A to fall from 0.10 M to 0.075 M?

For a zero order reaction,

Time, t = 1K[A- (A)]

or     t = 10.0030.10-0.075

    Time, t = 10.003×0.0251=253=8.3 seconds
