हिन्दीHigher yield of NO in \( \text{N}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{NO(g)} \) can be obtained at [\( \Delta H \) of the reaction \( = +180.7 \text{ kJ mol}^{-1} \)] A. higher temperature B. lower temperature C. higher concentration of \( \text{N}_2 \) D. higher concentration of \( \text{O}_2 \) Choose the correct answer from the options given below:
Correct answer · Option 4
A, C, D only
Explanation
Since the forward reaction is endothermic (\( \Delta H > \text{+ve} \)), higher temperature favors it. Also, higher concentrations of reactants (\( \text{N}_2 \) and \( \text{O}_2 \)) shift equilibrium to the right.
