In the reaction equilibrium
`N_(2)O_(4) hArr 2NO_(2)(g)`
When `5` mol of each is taken and the temperature is kept at `298 K`, the total pressure was found to be `20` bar.
Given : `Delta_(f)G_(n_(2)O_(4))^(ɵ)=100 kJ, Delta_(f)G_(NO_(2))^(ɵ)=50 KJ`
a. Find `DeltaG` of the reaction at `298 K`.
b. Find the direction of the reaction.

Explanation

To solve the problem step-by-step, we will follow the outlined approach:

### Step 1: Write the Reaction and Given Data
The equilibrium reaction is:
\[ N_2O_4 \rightleftharpoons 2NO_2 \]

Given data:
- Moles of \( N_2O_4 = 5 \, \text{mol} \)
