Question

The rate of a certain reaction increases by $2.3$ times when the temperature is raised from $300Kto310K.$ If $K$ is the rate constant at $300K$, then the rate constant at $310K$ will be:

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

Answer 1

Answer: (D)

$2.3K$

The rate of reaction is dependent on temperature. This is expressed in terms of temperature coefficient which is a ratio of two rate constants differs by a temperature of 10.

As given,

$2.3=\frac{K_{310}}{K_{300}}$

$K_{310}=2.3K_{300}$
