Entropy
Which of the following are true statements? a) For the reactionCO2(g) CO2(s) entropy increases b) For thereaction NaCl(s) + H2O(l) NaCl(aq) entropyincreases c) Molecules ofCl2(g) should have have greater entropy per mole thanmolecules of SO2(g) d) If entropydecreases for a certain spontaneous process, the entropy of theuniverse increases Entropy

Explanation / Answer

a) is not true because by making a gas into a solid you aredecreasing the amount of chaos within the system. b) is true because turning a solid into a gas is increasingthe chaos or entropy within the system. c) is not true, Cl2 is a homogenous gas whereas SO2 isheterogeneous therefore having more entropy. d) is true because it doesn't matter what you do, the entropyof the universe ALWAYS increases.
