Assertion (A) : For `N_(2)(g)+3H_(2)(g) hArr 2NH_(3)(g)`, the equilibrium constant is `K`. The for `1/2 N_(2)(g)+3/2H_(2)(g) hArr NH_(3)(g)`, the equilibrium constant will be `sqrt(K)`.
Reason (R) : If concentrations are changed to half, the equilibrium constants will be halved.
A. If both (A) and (R) are correct, and (R) is the correct explanation for (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 (A) is incorrect, but (R) is correct.
