Fe2O3(s) + 3H2(g) = 2Fe(s) + 3H2O(g) Part a: Use delta g values =frm a reference to calculate delta g for the reaction. =Delta G = 53 kj/mol Part b: Is this reaction spontaneous under standard conditions at 298k? Delta g is positie, so no. Part c: The value of Delta H for this reaction is 100.kj. At what temperature is this reaction spontaneous at standard conditions? Assume that delta H and delta S do not depend on temperatures? (So my question is how do u rearrange the formula ΔG=ΔH-TΔS to solve for the variable ΔS and also what is the answer for part c, i dont understand.

Fe2O3(s) + 3H2(g) = 2Fe(s) + 3H2O(g)

Part a:

Use delta g values =frm a reference to calculate delta g for the reaction.

=Delta G = 53 kj/mol

Part b:

Is this reaction spontaneous under standard conditions at 298k?

Delta g is positie, so no.

Part c:

The value of Delta H for this reaction is 100.kj. At what temperature is this reaction spontaneous at standard conditions? Assume that delta H and delta S do not depend on temperatures?

(So my question is how do u rearrange the formula ΔG=ΔH-TΔS

to solve for the variable ΔS and also what is the answer for part c, i dont understand.
