Statement 1: For the sequential reactions: A $\to$ B and B $\to$ C (both occurring completely), in which B has the same n-factor in both steps, the number of g-equivalents of A and C are equal.
Statement 2: The number of g-equivalents of a substance equals its mass divided by its equivalent weight.

Statement 1: For the sequential reactions: A $\to$ B and B $\to$ C (both occurring completely), in which B has the same n-factor in both steps, the number of g-equivalents of A and C are equal.

Statement 2: The number of g-equivalents of a substance equals its mass divided by its equivalent weight.

TestHub · Accepted Answer

I is correct: g-eq of A = g-eq of B (step 1) and g-eq of B = g-eq of C (step 2); when B keeps the same n-factor in both steps, these chain to give g-eq of A = g-eq of C. II is also correct - it is the definition of a g-equivalent - but it is a general definition, not the reason the chaining works, so II does not explain I. Hence (b).
