Question

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

• A. 2k
• B. k
• C. 2.3k
• D. $3k^2$

Answer 1

The correct option is C 2.3k

Since $k\propto T$.

$\frac{k_{310}}{k_{300}}=temperaturecoefficient$

Hence, $k_{310K}=2.3k_{300K}$
