Change in Gibbs
1- Calculate the change in Gibbs free energy for each of the following sets of ΔH ° rxn , ΔS ° rxn , and T .
Part A : ΔH ° rxn =- 122kJ ; ΔS ° rxn = 248J/K ; T= 298K
Part B : ΔH ° rxn = 122kJ ; ΔS ° rxn =- 248J/K ; T= 298K
Part C : ΔH ° rxn =- 122kJ ; ΔS ° rxn =- 248J/K ; T= 298K Express your answer using two significant figures.
Part D : ΔH ° rxn =- 122kJ ; ΔS ° rxn =- 248J/K ; T= 562K Express your answer using two significant figures.
