Question

The rate of a certain reaction increases by 2.3 times when the temperature is raised from 300 K to 310K. If k is the rate constant at 300 K then the rate constant at 310 K will be equal to

• A. 2 k
• B. k
• C. 2.3 k
• D. $3 k^2$

Answer 1

Answer: (C)

2.3 k

Answer 2

This is as per definition of temperature co-efficient Temp .co-eff.$\frac{k_{310}}{k_{300}}=2.3$ or $2r=k[2^3\,A]^n \, n= 1/3$
