Some reactions yield greater amount of products on heating while some others give lesser amount. Why ?

Explanation

To understand why some reactions yield a greater amount of products upon heating while others yield less, we need to consider the principles of chemical equilibrium and the effect of temperature on the equilibrium constant (K).

### Step-by-Step Solution:

1. **Understanding Chemical Equilibrium**:
- In a chemical reaction, reactants can convert to products and vice versa. When the rates of the forward and reverse reactions are equal, the system is said to be in equilibrium.

2. **Role of Enthalpy (ΔH)**:
