Given the values of ΔHrxn, ΔSrxn, and T below, determine ΔSuniv.

a) ΔHrxn = 87 kJ , ΔSrxn = 146 J/K , T= 296 K, will this be spontaneous or not spontaneous?

b) ΔHrxn = 87 kJ , ΔSrxn = 146 J/K , T= 762 K, will this be spontaeous or not spontaneous?

c) ΔHrxn = 87 kJ , ΔSrxn = −46 J/K , T= 296 K, will this be spontaneous or not spontaneous?

d) ΔHrxn = −87 kJ , ΔSrxn = 146 J/K , T= 390 K, will this be spontaneous or not spontaneous?
