Write the equilibrium constant expressions for the following reactions.
` N_2(g) +O_2(g)hArr 2NO(g) `

Explanation

To write the equilibrium constant expression for the reaction \( N_2(g) + O_2(g) \rightleftharpoons 2NO(g) \), we will follow these steps:

### Step 1: Identify the Products and Reactants
In the given reaction, the reactants are \( N_2(g) \) and \( O_2(g) \), and the product is \( NO(g) \).

### Step 2: Write the General Form of the Equilibrium Constant Expression
The equilibrium constant expression \( K \) is defined as the ratio of the concentrations (or partial pressures) of the products to the reactants, each raised to the power of their coefficients in the balanced equation.
