Question

In hte following reaction
$2 S O_{2} (g) + O_{2} (g) ⇌ 2 S O_{3} (g)$
the equilibrium is not attained. The rate of forward reaction is greater than that of backward reaction. Thus, which of the following is the correct relation between $K_{p}$ and $Q_{p}$ ?

Solution

The correct option is C $Q_{p} < K_{p}$
As the rate of forward reaction is greater than that of backward reaction, the reaction must proceed in the forward direction. Hence, $Q_{P} < K_{P}$

Q. Assertion :For the reaction

A (g) ⇌ B (g) + C (g)

K_{p} = 1 a t m

. If we start with equal moles of all gases at 9 atm of initial pressure, then at equilibrium partial pressure of A increases. Reason: Reaction quotient

Q_{p} > K_{p}

hence equilibrium shifts in a backward direction.
