What is van't Hoff reaction isotherm ?

Explanation

### Step-by-Step Solution for Van't Hoff Reaction Isotherm

1. **Definition of Van't Hoff Reaction Isotherm**: The Van't Hoff reaction isotherm relates the change in Gibbs free energy (ΔG) of a chemical reaction to its equilibrium constant (K_eq) at a given temperature. It provides a way to understand how the Gibbs free energy changes as a reaction approaches equilibrium.

2. **Gibbs Free Energy Change**: The change in Gibbs free energy for a reaction can be expressed as:
\[ \Delta G = \Delta G^\circ + RT \ln Q_c \]
