###### Problem Details

A reaction has a standard entropy change of +32.83 J/K and a standard enthalpy of +8.10 kJ. At what temperature is the reaction spontaneous? Assume the enthalpy and entropy of reaction are independent of temperature.

a) Spontaneous when T > 246.7 K

b) Spontaneous when T < 246.7 K

c) Spontaneous when T > 25 K

d) The reaction is non-spontaneous at all temperatures

e) The reaction spontaneous at all times
