NEET (UG) 2024 — Question 73

Activation energy of any chemical reaction can be calculated if one knows the value of

Answer: D

To calculate value of $\mathrm{E}_{\mathrm{a}}$

Equation used is

\log \left(\frac{k_{2}}{k_{1}}\right)=\frac{E_{a}}{2.303 R}\left(\frac{1}{T_{1}}-\frac{1}{T_{2}}\right)

Hence $E_{a}$ can be calculated if value of rate constant $k$ is known at two different temperatures

$T_{1}$ and $\mathrm{T}_{2}$ .
