Statement 1: For the sequential reactions: A $\to$ B and B $\to$ C (both occurring completely), the number of g-equivalents of A and C must be equal.
Statement 2: The relation between the number of g-equivalents of A and C depends on the equivalent weight of B in both the reactions.

Question

Statement 1: For the sequential reactions: A $\to$ B and B $\to$ C (both occurring completely), the number of g-equivalents of A and C must be equal.

Statement 2: The relation between the number of g-equivalents of A and C depends on the equivalent weight of B in both the reactions.

I is incorrect in general: g-eq of A = g-eq of B (step 1) and g-eq of B = g-eq of C (step 2) hold only stepwise; the g-eq of A and C are equal only if B has the same n-factor (equivalent weight) in both steps. For example, if B is an oxidant with n = 2 in step 1 but n = 1 in step 2, the g-equivalents of A and C differ by a factor of 2, so equality is not forced. II is correct: the relation does depend on B's equivalent weight (n-factor) in the two reactions. Hence (d).
