Using data from the appendix, calculate ΔS o rxn and ΔSsurr for each of the reactions and determine if each is spontaneous at 25°C. (a) 2 KClO4(s) → 2 KClO3(s) + O2(g) ΔS o rxn = J/K ΔS o surr = J/K Is the reaction spontaneous at 25°C? yes no (b) 2 Na(s) + 2 H2O(l) → 2 NaOH(aq) + H2(g) ΔS o rxn = J/K ΔS o surr = × 10 J/K (enter your answer in scientific notation) Is the reaction spontaneous at 25°C? yes no (c) N2(g) → 2 N(g) ΔS o rxn = J/K ΔS o surr = × 10 J/K (enter your answer in scientific notation) Is the reaction spontaneous at 25°C? yes no
