Methane gas is completely combusted the products are carbon dioxide gas and water gas. What statement can be correctly made regarding the entropy change of this reaction?
- The entropy of the reaction is increasing because there are more moles of gaseous products than moles of gaseous reactants.
- The entropy of the reaction is increasing because there are fewer moles of gaseous products than moles of gaseous reactants.
- The entropy of the reaction remains constant because there are an equal number of moles of gaseous products and gaseous reactants.
- The entropy of the reaction is decreasing because there are more moles of gaseous products than moles of gaseous reactants.
- The entropy of the reaction is decreasing because there are fewer moles of gaseous products than moles of gaseous reactants.
