What is the Gibbs Helmhotz equation ?

Explanation

**Step-by-Step Solution:**

1. **Identify the Gibbs Helmholtz Equation**: The Gibbs Helmholtz equation is a fundamental equation in thermodynamics that relates the change in Gibbs free energy (ΔG) to the change in enthalpy (ΔH) and the change in entropy (ΔS) of a system.

2. **Write the Equation**: The Gibbs Helmholtz equation is expressed as:
\[ \Delta G = \Delta H - T \Delta S \]
