Question
**Consider the Reaction:**

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

Write the equilibrium constant for this reaction in terms of the equilibrium constants, \( K_1 \) and \( K_2 \), for the reactions below:

\[ \text{N}_2(g) + 2\text{O}_2(g) \rightleftharpoons \text{N}_2\text{O}_4(g) \quad K_1 \]

\[ \frac{1}{2}\text{N}_2(g) + \text{O}_2(g) \rightleftharpoons \text{NO}_2(g) \quad K_2 \]

*For answers with both a subscript and a superscript, enter the subscript first. For example, enter \( K^2_1 \) if the first equilibrium constant should be squared.*

\[ K = \boxed{} \]

Expert Solution
Step 1

• Equilibrium constant for reverse reaction:

For reverse reaction the value of the equilibrium constant is the reciprocal of the equilibrium constant for forward reaction.

• Equilibrium constant of added reaction:

Suppose if two reactions are added to give new reaction in that case the equilibrium constant of a new reaction is the product (multiplication) of equilibrium constants of reaction added.


• Equilibrium constant when coefficient are changed:

If a balanced chemical equation coefficient are multiplied by factor n, then  the original Equilibrium constant (K) is raised to the nth power to obtain the new equilibrium constant value.
