10 % sites of catalyst bed have adsorbed by `H_(2)` on Heating `H_(2)` gas is evloved from sites and collected at 0.03 atm and 300 K in a small vessel of `2.46 cm^(3)`.
no. of sites available is `5.4 xx 10^(16) ` per `cm^(2)` and surface area is `1000 cm ^(2)` . find out the no. of suface sites occupied per molecule of `H_(2)`.

Options

A. 1
B. 2
C. 3
D. None of these

Explanation

To solve the problem step by step, we will follow the instructions provided in the video transcript and perform the necessary calculations.

### Step 1: Calculate the number of moles of H₂ evolved

Using the ideal gas equation, we can find the number of moles (n) of H₂ gas collected:

\[
PV = nRT
