Question

If pressure increases then its effect on given equilibrium $2NO(g)\rightleftharpoons N_2(g)+O_2(g)$ is shift in :

• A. forward direction
• B. backward direction
• C. no effect
• D. none of the above

Answer 1

Answer: (C)

According to Le-Chatelier principle the reactions in which number of moles of reactants is equal to number of moles of products, is not effected by change in pressure.
$2NO(g)\rightleftharpoons N_2(g)+O_2(g)$
Moles of reactants $=2$ Moles of products $=2$
$\because$ There is no change in number of moles of reactants and products.
$\therefore$ The reaction is not effected by change in pressure.
