Above what temperature does the following reaction become nonspontaneous? 2H_2S(g) + 3 O_2(g) rightarrow 2 SO_2(g) + 2 H_2O(g) Delta H = -1036 kJ; Delta S = -153.2 J/K A) 298 K B) 158.7 K C) 6.762 times 10^3 K D) This reaction is nonspontaneous at all temperatures. E) This reaction is spontaneous at all temperatures. Calculate Delta S degree_rxn for the following reaction. The S degree for each species is shown below the reaction. C_2H_2(g) + H_2(g) rightarrow C_2H_4(g) S degree(J/mol degree K) 200.9 130.7 219.3 A) +550.9 J/K B) -112.3 J/K C) +112.3 J/K D) -550.9 J/K E) +337.1 J/K
