Question

What reaction would cause a decrease in entropy?

Answer 1

B.

Step-by-step explanation:

if the # of molecules (of gas) on the product side is less than # of molecules on the reactant side = entropy is decreasing, and vice versa.

if the # of molecules on the reactant side is less than # of molecules on the product side = entropy is increasing (it is more disorderly, chaotic)

A. 2 → 2 + 1 entropy increases

B. 1 + 4 → 1 + 1 entropy decreases

C. 2 → 1 + 3 entropy increases

D. 2 + 1 → 2 + 2 entropy increases

Answer 2

B

Step-by-step explanation:

liquids is produce therefore it will have the less Entropy
