**Chemical Equilibrium Problem: Determining the Equilibrium Molarity**Suppose a 250. mL flask is filled with 0.40 mol of \( \text{O}_2 \) and 0.10 mol of \( \text{NO} \). The following reaction becomes possible:\[ \text{N}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{NO}(g) \]The equilibrium constant \( K \) for this reaction is 7.40 at the temperature of the flask.**Task:**Calculate the equilibrium molarity of \( \text{N}_2 \). Round your answer to two decimal places.**Solution Input Box:**\( \boxed{ \text{M} } \) \( \quad \quad \: \)[ x ] \(\quad\) [ ↻ ] \(\quad\) [ ? ]This educational example demonstrates how to use the equilibrium constant to find the equilibrium concentration of a reactant or product in a chemical reaction. **Approach:**1. Calculate initial concentrations by dividing moles by volume (0.250 L).2. Use the equilibrium constant expression derived from the balanced chemical equation.3. Set up and solve the equation for the unknown concentration at equilibrium.4. Round the final answer to two decimal places.Through this process, students can practice applying their knowledge of chemical equilibria and stoichiometry.
