Question

A higher yield of NO in \mathrm{N2(g) + O2(g) \rightleftharpoons 2NO(g)} can be obtained at [\Delta H of the reaction = +180.7\ \mathrm{kJ\,mol^{-1}}]:

A. Higher temperature · B. Lower temperature · C. Higher concentration of \mathrm{N2} · D. Higher concentration of \mathrm{O2}

Choose the correct answer from the options given below:

Vishal Gupta · Accepted Answer

D. The reaction is endothermic, so higher temperature shifts it forward (A). Adding either reactant also pushes it forward (C, D). Lower temperature would reduce the yield. Hence A, C and D.
