The correct Answer is:
To understand the concept of equilibrium in the reaction \( N_2 + O_2 \rightleftharpoons 2NO \), we can break it down step by step: ### Step-by-Step Solution: 1. **Understanding the Reaction**: - The reaction involves nitrogen gas (\( N_2 \)) and oxygen gas (\( O_2 \)) combining to form nitrogen monoxide (\( NO \)). 2. **Defining Equilibrium**: - Equilibrium in a chemical reaction occurs when the rates of the forward and backward reactions are equal. This means that the rate at which \( N_2 \) and \( O_2 \) are converted into \( NO \) is the same as the rate at which \( NO \) is converted back into \( N_2 \) and \( O_2 \). 3. **Rate of Reactions**: - Let \( R_f \) be the rate of the forward reaction (formation of \( NO \)) and \( R_b \) be the rate of the backward reaction (conversion of \( NO \) back to \( N_2 \) and \( O_2 \)). At equilibrium: \[ R_f = R_b \] 4. **Constant Concentrations**: - At equilibrium, the concentrations of the reactants (\( N_2 \) and \( O_2 \)) and the product (\( NO \)) remain constant over time. This does not mean that the concentrations are equal, but rather that they do not change as the forward and backward reactions continue to occur at the same rate. 5. **Dynamic Nature of Equilibrium**: - It is important to note that equilibrium is a dynamic state. Even though the concentrations are constant, both the forward and backward reactions are still occurring. 6. **Conclusion**: - Therefore, in the context of the reaction \( N_2 + O_2 \rightleftharpoons 2NO \), equilibrium means that the rate of formation of \( NO \) equals the rate of its decomposition back into \( N_2 \) and \( O_2 \), resulting in constant concentrations of all substances involved. ### Final Answer: Equilibrium in the reaction \( N_2 + O_2 \rightleftharpoons 2NO \) means that the rate of the forward reaction is equal to the rate of the backward reaction, leading to constant concentrations of reactants and products. ---
