Question

The rate constant of the reaction A gives out B is 0.6×10*-3mol/lit.if the conc of A is 0.5M,then conc.of B after 20min.is

Answer 1

Reaction's order will be zero and rate constant's unit is mole per second.

K = [ A ]0 - [ A ] / t

0.6 × 10 ^–3 = 5 - [ A ] / 20 x 60

[ A ] = 5 - 0.72

Conc. of B after 20 minutes will be 0.72 M.
