Explanation:

The half life period of a first order reaction is 20 minutes.

t

1/2

=20 minutes.

The rate constant, k=

t

1/2

0.693

=

20min

0.693

=0.03465/min

The time required for the concentration of the reactant to change from 0.16M to 0.02M

is t=

k

2.303

log

a−x

a

=

0.03465/min

2.303

log

0.02

0.16

=60min
