### Exothermic Reaction Analysis

**Reaction:**

\[ C_6H_{12}O_6(s) + 6 O_2(g) \rightleftharpoons 6 CO_2(g) + 6 H_2O(g) \]

**Question:** 

Predict the effect (shift right, shift left, or no effect) of increasing and decreasing the reaction temperature. How does the value of the equilibrium constant depend on temperature?

**Explanation:**

In an exothermic reaction, heat is released. According to Le Chatelier's principle, if the temperature is increased, the system will adjust to counteract this change. Therefore:

- **Increasing Temperature:** The equilibrium will shift to the left to absorb the excess heat.
- **Decreasing Temperature:** The equilibrium will shift to the right to produce more heat.

**Equilibrium Constant Dependence:**

For exothermic reactions, the equilibrium constant decreases with an increase in temperature because the reaction shifts towards reactants. Conversely, the equilibrium constant increases when the temperature decreases, as the reaction favors the formation of products.

This analysis is crucial for understanding how temperature variations impact reaction dynamics and equilibrium positions in chemical processes.
