What is meant by entropy driven reaction? How can the reaction with positive change of enthalpy and entropy driven?

Explanation

To understand what is meant by an entropy-driven reaction and how a reaction with a positive change in both enthalpy (ΔH) and entropy (ΔS) can be spontaneous, we can break down the concepts step by step.

### Step-by-Step Solution:

1. **Understanding Spontaneity**:
- A reaction is considered spontaneous if it occurs without needing to be driven by an external force. For a reaction to be spontaneous, the change in Gibbs free energy (ΔG) must be negative.
- The relationship between Gibbs free energy, enthalpy, and entropy is given by the equation:
\[
