Gibbs free energy in chemistry is symbolized G. It is related to the enthalpy (H) and entropy (S) changes in the reaction by the following equation. AG° = AH° - TASº. °= standard conditions 1. (2) a) Does entropy increase or decrease (circle one) in the following chemical reaction? 2 Al (s) + 3 H2SO4 (aq) → Al:(SO4)3 (aq) + 3 H2 (g) (4) b) Using the standard enthalpies of formation for the substances in this equation, calculate the AH°t for the reaction. AH°t H2SO4 (aq) -50.7 kJ/mol AH° Al2(SO4)3 (aq) -3150 kJ/mol Show your work. ΔΗ'rcaction kJ 'c) Is this reaction expected to be spontaneous under standard conditions? yes or no or can't tell (circle one) d) To predict a spontaneous reaction, what must be the sign of AG°reaction ?
