Le chatelier's principle is applicable to

Options

A. Chemical equilibria only
B. Physical equilibria only
C. Both physical and chemical equilibria
D. Only homogenous chemical reversible reactions

Answer

**Step-by-Step Solution:**

1. **Understanding Le Chatelier's Principle**: Le Chatelier's Principle states that if a system at equilibrium is disturbed by changing the conditions (such as concentration, temperature, or pressure), the system will respond by shifting the position of equilibrium to counteract the change and restore a new equilibrium.

2. **Types of Equilibria**: The principle applies to both chemical equilibria (reactions that can proceed in both forward and reverse directions) and physical equilibria (such as phase changes, like solid-liquid or liquid-gas).

3. **Application to Chemical Equilibria**: In a chemical reaction at equilibrium, if the concentration of a reactant is increased, the system will shift to the right to produce more products. Conversely, if the concentration of a product is increased, the system will shift to the left to produce more reactants.

4. **Application to Physical Equilibria**: For physical processes, such as the equilibrium between ice and water, if the temperature is increased, the equilibrium will shift to favor the endothermic process (melting of ice), thus producing more water.

5. **Conclusion**: Le Chatelier's Principle is applicable to all systems that are in equilibrium, whether they are chemical or physical. Therefore, the correct answer to the question is that Le Chatelier's Principle is applicable to both physical and chemical equilibria.

**Final Answer**: Le Chatelier's Principle is applicable to both physical and chemical equilibria.
