Q. In a gaseous reversible reaction, $N_{2} + O_{2} \rightleftharpoons 2NO + heat$ If pressure is increased then the equilibrium constant would be
A) Unchanged
B) Increased
C) Decreased
D) Sometimes increased, sometimes decreased
Explanation
(a)
When the number of moles of gaseous reactants and products is same, then equilibrium is not affected by pressure and hence, the equilibrium constant is unaffected.
