Question

Which order reaction obey the expression t
1/2=
Ka
First
Second
Third
Zero​

Answer 1

Answer:

For n

th

order reaction, the relationship between the half life period and the concentration is t

1/2

=

k.a

n−1

1

.

But t

1/2

=

k.a

1

Hence, n−1=1 or n=2.

Hence, for a second order reaction, the half life period is inversely proportional to the concentration.
