10. Would you expect each of the following reactions to be spontaneous at low temperatures, high temperatures, all temperatures, or not at all? Explain. (a) PCl3(g) + Cl2(g) --> PCIs(g) AH = -87.9kJ (b) 2NH3(g)--> N2(g) + 3H2(g) (c) 2N2O(g) --> 2N2(g) + O2(g) 11. Please indicate if TRUE or FALSE: a. The entropy of a gas increases with increasing temperature. b. Spontaneous processes always increase the entropy of the reacting system. c. All spontaneous processes release heat to the surroundings d. An endothermic reaction is more likely to be spontaneous at high temperatures than at low temperatures. e. The entropy of sugar decreases as it precipitates from an aqueous solution. AH = +92.2kJ AH-164.1kJ 12. Consider the following reaction: N(g)+3H(g) --->2NH3(g) If AH = -92.2kJ and AS= -0.1987kJ/K, what is AG for the reaction at 475C and at 5C? Provide the answer in kJ. In each case, is the reaction spontaneous
