em 11 Review Constants ! Predict the spontaneity of a reaction (and the temperature dependence of the spontaneity) for each possible combination of signs for AH and AS (for the system). Part A A negative, AS positive The reaction will be spontaneous at low temperature, but nonspontaneous at high temperature, The reaction will be nonspontaneous at all temperatures. The reaction will be spontaneous at all temperatures. The reaction will be nonspontaneous at low temperature, but spontaneous at high temperature. Submit...
If AH and AS are both negative for a reaction, then the reaction is O nonspontaneous at all temperatures. O nonspontaneous at low temperatures and spontaneous at high temperatures. O spontaneous at all temperatures. O spontaneous at low temperatures and nonspontaneous at high temperatures.

AH 24. (3 pts.) Fill in the blanks with (4, -,0) for the value of each situation below: AS AG endothermic Less disorder At equilibrium exothermic Same disorder Non-spontaneous adiabatic More disorder Spontaneous
For the reaction 2C4H10 (g) + 1302 (8) — 8CO2 (g) + 10H20 (g) AH° is -125 kJ/mol and AS is -253 J/K mol. This reaction is spontaneous at all temperatures spontaneous only at high temperature © spontaneous only at low temperature nonspontaneous at all temperatures None of the above
