Question

**Problem Statement:**

Determine ΔG for the phase change $ \text{N}_2 + 3\text{H}_2 \rightarrow 2 \text{NH}_3 $ at 25°C.

**Given Data:**
- ΔH° = -80 kJ/mol
- ΔS = +100 J/mol·K

**Note:**
- The problem requires you to calculate the Gibbs free energy change (ΔG) for the given reaction at 25°C.
- Remember to convert all units appropriately, such as converting ΔS from J to kJ when calculating ΔG using the formula: ΔG = ΔH - TΔS.

Expert Solution

Step 1 Introduction interpretation

Interpretation -

To determine the $∆$ G for the phase change for the given reaction N₂ + 3H₂ $\overset{}{\to}$ 2NH₃

Concept-

$∆ G$ which is known as gibbs free energy , so to determine this gibbs free energy for phase change when enthalpy of reaction ( $∆ H$ ) and $(∆ S)$ are given so here is a relation that is -

$∆ G = ∆ H - T ∆ S$
