For a particular reaction, ΔH° is 20.1 kJ/mol and ΔS° is 45.9 J/(mol·K). Assuming these values change very little with temperature, over what temperature range is the reaction spontaneous in the forward direction?
The reaction is spontaneous for temperatures is greater than T=_____K
dG = dH - TdS
Set dG = 0 and solve for T(in kelvin). Don't forget that dH and dS are not the same unit; i.e., you must convert one of them to the other.
I found approximately 440 K
