Postby JaeHoCho1B » Sat Jan 28, 2017 6:26 pm

Hello! I was wandering for quiz preparation quiz 12 on page 116 that are we supposed to use the following equation?
delta G= delta H - T(Delta S). If yes, do we add all up the given delta H and subtract with the given Temperature times the sum of delta S.

**Sorry I can't post chart, but the question is: "Calculate the standard Gibbs free energy for the following reaction at 298 K. Fe2O3 + C(s, graphite)----->Fe(s) + CO2(g)

Yes, you would need to use Since you know that and , then we can use to find the standard Gibbs free energy. Don't forget to balance the equation!
