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

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but(R) is not the correct explanation of (A)
C. If(A) is correct, but (R) is incorrect
D. If both (A) and (R) are incorrect

Answer

B

Explanation

For the reaction: `aA + bB hArr x C + dD , K _(c ) = ([C ]^(c)[D]^(d))/([A] ^(a) [B] ^(b))`
For reverse reaction `: c C + d D hArr aA + bB , K _(c)’ = ([A] ^(a)[B]^(8b))/([C] ^(c) [D]^(d)) =(1)/(K _(c))`
