Question

if a reaction has more moles of gas on the products side compared to the reactants side, then the entropy ______ when that reaction happens.

increases

decreases

stays the same

Explanation:

Entropy is a measure of disorder or randomness. For gaseous reactions, an increase in the number of moles of gas (more moles on the product side) means more particles are moving freely, leading to greater disorder. So, entropy increases.

Answer:

A. increases
