The correct Answer is:
To solve the question regarding the equilibrium of the reaction \( N_2(g) + O_2(g) \rightleftharpoons 2NO(g) \), we will analyze the concept of chemical equilibrium step by step. ### Step 1: Understanding Chemical Equilibrium Chemical equilibrium occurs in a reversible reaction when the rates of the forward and reverse reactions are equal. This means that the concentration of reactants and products remains constant over time, even though both reactions are still occurring. ### Step 2: Analyzing the Given Reaction In the reaction \( N_2(g) + O_2(g) \rightleftharpoons 2NO(g) \): - The reactants are nitrogen gas (\( N_2 \)) and oxygen gas (\( O_2 \)). - The product is nitrogen monoxide (\( NO \)). ### Step 3: Concentration Changes at Equilibrium At equilibrium: - The concentration of \( N_2 \) and \( O_2 \) does not change, meaning they remain constant. - The concentration of \( NO \) also remains constant. ### Step 4: Evaluating the Options Now, let's evaluate the statements provided in the question: 1. **Concentration of reactant changes while concentration of product is constant** - This is incorrect because, at equilibrium, the concentrations are constant. 2. **Concentration of all substances is constant** - This is correct as all concentrations (reactants and products) remain unchanged at equilibrium. 3. **Concentration of reactant is constant while concentration of product changes** - This is incorrect because both reactants and products remain constant at equilibrium. 4. **Concentration of all substances changes** - This is incorrect because, at equilibrium, the concentrations do not change. ### Conclusion The correct answer is that at equilibrium, the concentration of all substances is constant. ### Final Answer **The correct statement is: Concentration of all substances is constant.** ---
