Assertion: The equilibrium constant for the reverse reaction is equal to the inverse of the equilibrium constant for the forward reaction. Reason: The value of equilibrium constant is independent of initial concentrations of the reactants and products.

For the reaction: aA +bB leftharpoons cC +dD Kc=([C]c[D]d/[A]a[B]b) For reverse reaction: cC +dD leftharpoons aA +bB K'c=([A]a[B]b/[C]c[D]d)=(1/Kc)

Q. Assertion : The equilibrium constant for the reverse reaction is equal to the inverse of the equilibrium constant for the forward reaction.
Reason : The value of equilibrium constant is independent of initial concentrations of the reactants and products.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

For the reaction : $a A + b B ⇌ c C + d D$
$K_{c} = \frac{[ C ] ^{c} [ D ] ^{d}}{[ A ] ^{a} [ B ] ^{b}}$
For reverse reaction : $c C + d D ⇌ a A + b B$
$K_{c}^{'} = \frac{[ A ] ^{a} [ B ] ^{b}}{[ C ] ^{c} [ D ] ^{d}} = \frac{1}{K _{c}}$
