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.)
And is A,B,C spontaneous or non spontaneous?
dHorxn = (n*dHoformation producs) - (n*dHoreactants)
dSo rxn = (n*dSo formation products( - (n*dSo formation reactants)
dGrxn = dHrxn - TdSrxn
dG>0 not spontaneous.
Im still confused..
is n 2?
and if so would it look like this for A
n stands for number of mols. It is 1 for CaO, 1 for CaCO3, and 1 for CO2.
Look up dHo formation CO2, CaO, and CaCO3. Calculate dHo reaction.
Look up dSo for CO2, CaO, and CaCO3. Calculate dSo reaction.
Then dGorxn = dHorxn - TdSorxn
