For the reaction, `N_2(g) + 3H_2(g) to 2NH_3(g) , predict whether the work is done by the system or on the system.

Explanation

To determine whether the work is done by the system or on the system for the reaction:

\[ N_2(g) + 3H_2(g) \rightarrow 2NH_3(g) \]

we can follow these steps:

### Step 1: Understand the Concept of Work in Thermodynamics
In thermodynamics, work is done by the system when the volume of the system increases, and work is done on the system when the volume of the system decreases.
