**Chemical Equilibrium Question**

In this exercise, you will calculate the equilibrium constant, \( K_c \), for the following chemical reactions based on provided data.

**Given Reactions:**

1. \( \frac{1}{2}\text{N}_2(g) + \text{O}_2(g) \rightleftharpoons \text{NO}_2(g) \)
   - \( K_c = 1.04 \times 10^{-3} \)

2. \( \text{N}_2(g) + 2\text{O}_2(g) \rightleftharpoons \text{N}_2\text{O}_4(g) \)
   - \( K_c = 7.42 \times 10^{-18} \)

**Tasks:**

Calculate \( K_c \) for each of the following reactions:

(a) \( 2\text{NO}_2(g) \rightleftharpoons \text{N}_2(g) + 2\text{O}_2(g) \)

(b) \( \text{N}_2(g) + 2\text{O}_2(g) \rightleftharpoons \text{N}_2\text{O}_4(g) \)

(c) \( 2\text{NO}_2(g) \rightleftharpoons \text{N}_2\text{O}_4(g) \)

**Note:** Assume that the reactions are at equilibrium and that the provided equilibrium constants are applicable. Use principles of chemical equilibrium to determine the relationship between the given and calculated \( K_c \) values.
