What is ΔS° for a reaction that produces 2 mol of gas from 1 mol of gas?
A.Positive
B.Negative
C.Zero
D.Impossible to determine
Explanation
Core Concept
More gas moles means more accessible microstates and greater dispersal, so ΔS° > 0. Count gas moles on each side to read the sign.
Correct Answer
APositive
