Question

For the reaction,$N_2{O}_4\left(g\right)\rightleftharpoons 2N{O}_2\left(g\right)$, at equilibrium,increase in pressure shifts the equilibrium in ___direction?

• A. $forward$
• B. $backward$
• C. $equilibrium$
• D. non of these

Answer 1

Answer: (B)

$backward$

When there is an increase in pressure, the equilibrium will shift towards the side of the reaction with fewer moles of gas. As in the reaction, reactant side has 1 mole while the product side has two moles of gas. Therefore it shifts the equilibrium in backward direction.
