Question

55. The rate constant of a first order reaction is
10 min-' at 300 K. The temperature
coefficient of the reaction is 2. What is the rate
constant of the reaction at 350 K
approximately?
1) 16 10-3
2)64 10-3
3) 32 10-3
4) 250​

Answer 1

Answer :

3

Solution :

Temperature coefficient =kT+10kT=2

With the increase of temperature 10∘C the rate of reaction is double.

k50=(2)5×10−3

k50=32×10−3
