Predicting Relative Entropy Values
Problem: Choose the member with the higher entropy in each of the following pairs, and justify your choice [assume constant temperature, except in(f)]:
(a) 1 mol NaCl(s) or 1 mol NaCl(aq)
(b) 1 mol SF6 or 1 mol SCl6
(c) 1 mol CO(g) or 1 mol CO2 (g)
(d) 1 mol S8 or 4 mol S2
(e) 1 mol H2O(s) or 1 mol H2O(g)
(f) Liptonís noodle soup at 24oC or at 95oC
Plan: The less ordered a system, the greater the entropy. A higher temperature increases entropy. Assume constant temperature in a-e.
