#### Answer

Entropy is expected to increase because a solid reactant is producing only a gas product. Gases have higher entropy than solids. Entropy is expected to increase because a single solid reactant is producing a gas product. Gases have higher entropy than solids. Entropy is expected to decrease because two moles of gaseous molecules reacts to form one mole of gaseous molecules. Entropy is expected to increase because one mole of gaseous molecules reacts to form two moles of gaseous molecules.
