Question
Use the standard free energy data in the Standard State Thermodynamic Data table to determine the free energy change for each of the following reactions (in kJ/mol), which are run under standard state conditions and 25°C. Identify each as either spontaneous or nonspontaneous at these conditions.
(a) C(graphite) + O2(g) → CO2(g)
ΔG°= ??? kJ/mol --> Do not know how to figure this??? Need answer and explanation.
I know this is spontaneous.
(b) N2O(g) + O2(g) → N2O3(g)
ΔG°= ??? kJ/mol --> Do not know how to figure this??? Need answer and explanation.
I know this is nonspontaneous.
(c)
PCl3(l) + Cl2(g) → PCl5(g)
ΔG°= ??? kJ/mol --> Do not know how to figure this??? Need answer and explanation.
I know this is spontaneous.
(d)Cr2O3(s) + 3 CO(g) → 2 Cr(s) + 3 CO2(g)
ΔG°= ??? kJ/mol --> Do not know how to figure this??? Need answer and explanation.
I know this is nonspontaneous.
(f) LiI · 2 H2O(s) → LiI(s) + 2 H2O(g)
For this part only, use the following data.
LiI · 2 H2O(s) = ΔG⁰298 = −780.3 kJ/mol
LiI(s) = ΔG⁰298 = −270.3 kJ/mol
H2O(g)= ΔG⁰298 = −228.6 kJ/mol
LiI(s) = ΔG⁰298 = −270.3 kJ/mol
H2O(g)= ΔG⁰298 = −228.6 kJ/mol
ΔG°= ??? kJ/mol --> Do not know how to figure this??? Need answer and explanation.
I know this is nonspontaneous.
