Consider the following reaction:
Estimate ΔG∘ for this reaction at each of the following temperatures. (Assume that ΔH∘ and ΔS∘ do not change too much within the given temperature range.)
A) 310K and is it spontaneous
B) 1070K and is it spontaneous
C) 1470K and is it spontaneous
Look up dHo formation and dSo formation.
Then dHo rxn = (n*dHo products) - (dHo reactants)
dSo rxn = (n*dSo products) - (n*dSo reactants)
Then dG = dH - TdS for each temperature
dG = - number is spontaneous
dG = + number is not spontaneous.
