Question

Plots showing the variation of the rate constant $\left(k\right)$ with temperature $\left(T\right)$ are given below. The plot that follows Arrhenius equation is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

According to the Arrhenius equation, $k=A{e}^{-Ea/RT}$ where, $k=\text{rate constant},E_a=\text{activation energy and}T=\text{temperature}$.
Increasing the temperature, leads to doubling of the rate of reaction alongwith decrease in activation energy and an exponential increase in the rate constant.
