The dissociation energy of `H_(2)` is `430.53 kJ mol^(-1), `If `H_(2)` is dissociated by illuminating with radiation of wavelength `253.7 nm` , the fraction of the radiant energy which will be converted into kinetic energy is given by

Options

A. `8.56 %`
B. `2.33 %`
C. `1.3%`
D. `90%

Explanation

To solve the problem, we need to calculate the fraction of the radiant energy that is converted into kinetic energy when \( H_2 \) is dissociated by radiation of wavelength \( 253.7 \, \text{nm} \). Here are the steps:

### Step 1: Calculate the Energy of a Photon
The energy of a photon can be calculated using the formula:

\[ E = \frac{hc}{\lambda} \]
