If we take one mole of each of the four gases in one-litre container, what would be the equilibrium concentration of NO and `NO_2?`

Explanation

To solve the problem of finding the equilibrium concentrations of NO and NO2 when one mole of each of the four gases is placed in a one-liter container, we can follow these steps:

### Step 1: Write the Reaction
The reaction involving the gases is:
\[ SO_2 + NO_2 \rightleftharpoons SO_3 + NO \]

### Step 2: Set Up Initial Concentrations
Since we have one mole of each gas in a one-liter container, the initial concentrations of each gas are:
...
