Q. Higher yield of NO in N$_2$(g) + O$_2$ $\rightleftharpoons$ 2NO(g) can be obtained at [$\Delta$H of the reaction = + 180.7 kJ mol$^{-1}$] A. higher temperature B. lower temperature C. higher concentration of N$_2$ D. higher concentration of O$_2$ Choose the correct answer from the options given below:
A) A, D only
B) B, C only
C) B, C, D only
D) A, C, D only
Explanation
[Solution by Claude - not from source] The reaction is endothermic, so higher temperature favours NO. Increasing reactant concentrations ($N_2$ or $O_2$) also shifts equilibrium forward. So A, C, D. Answer (4).
