Answer to Question #77037 in Physical Chemistry for Jimmy

Question

For the reaction
4Ag(s) + O2(g) = 2Ag2O(s) at 25 oC and 1 atm pressure,
ΔHo is -61140 J andΔSo is 132 J/K.
Assuming that ΔHo and ΔSo are essentially temperature independent, which of the following statements is true?



A) The reaction will not be spontaneous at any
temperature.

B) The reaction will be spontaneous at all
temperatures.

C) The reaction will be spontaneous at low temperatures,
and the reverse reaction will be spontaneous at high
temperatures.

D) The reaction will be spontaneous at high temperatures,
and the reverse reaction will be spontaneous at low
temperatures.

E) The change in entropy is the driving force at low
temperatures.
