Explanation Given: a. b. c. d. When a solid becomes a liquid, its entropy will increase. When a liquid becomes a gas, its entropy will increase. The entropy of a gas is much greater than that for a liquid and a solid, which has an entropy larger than that of solid. The entropy change is the entropy difference between products and reactants, if there are more gas moles on the products side than those on the reactants side then ∆S sys must have a positive sign a. There is no gas on the products side; there is 1 mole of gas on the reactants side, so it is correct to say that the entropy of reactants is greater than that of products therefore the ∆S sys must be negative...
