a. (4 pt) The entropy of the products for a given chemical reaction is greater than the entropy of the reactants. The reaction must then be spontaneous. True or False? Provide a thorough and to-the-point rationale for your answer b. (5 pt) Order the following solids in terms of lowest to highest standard molar entropy S (J/Kmol): KCI, CsCI, LICI, NaCl, RbCi. C. (3 pt) Methane, CH4, vaporizes from liquid to gas at -161 C. The molar enthalpy of vaporization of methane (AHvaporization) of methane is 8.17 x 103 Joule/mole. What is the molar entropy of vaporization (Svaporization of methane
