Question

70 % of a first order reaction is completed in 23 minute calculate rate of a reaction​

Answer 1

Answer:

As this is a first order reaction we can use k

1

=

t

2.303

log

a−x

a

to get value of k

1

.

So putting value is above equation we get k

1

=

70

2.303

log

0.3

1

Hence, k

!

=0.017

Now to calculate half-life we can use t

1/2

=

k

0.693

Putting values in above equation we get
