Class 11 NEET Chemistry Equilibrium Questions Part 2

Yield of the product generally depends on
- Temperature
- Concentration of reactant(s) and product(s)
- Pressure
As this is an endothermic reaction ( ∆H=+180.7‌kJ‌mol−1 ), so, increase in temperature will shift equilibrium in forward direction to increase yield of NO.
Increase in concentration of reactants ( N2 and O2 ) also shifts the equilibrium in forward direction and increase the yield of NO.
Hence, (A), (C) and (D) only will increase yield of NO.
