Q.
Activation energy of any chemical reaction can be calculated if one knows the value of [2024]

1 rate constant at standard temperature

2 probability of collision

3 orientation of reactant molecules during collision

4 rate constant at two different temperatures

Ans.
(4)

The activation energy of a reaction can be determined by evaluating the rate constant at two different temperatures by using the following expression:

$\log \frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303 R} [\frac{T_{2} - T_{1}}{T_{1} T_{2}}]$

Solution
