Match the following Column A to Column B

Options

A. Activation energy of forward reaction is `E_(1)+E_(2)` and product is less stable than reactant
B. Activation energy of forward reaction is `E_(1)+E_(2)` and product is more stable than reactant
C. Activation energy of both forward and backward reaction is `E_(1)+E_(2)` and reactant is more stable than product
D. Activation energy of backward reaction is `E_(1)` and product is more stable than reactant

Answer

A

Explanation

Activation energy is the minimum energy required to convert reactant molecules to product molecules. Here, the energy gap between reactants and activated complex is sum of `E_(1)` and `E_(2)`.
`:.` Activation energy `=E_(1)+E_(2)`
Product is less stable than reactant as energy of product is greater than the reactant.
