Question

Q7. The standard free energies of formation H2S (g) and CdS (s) at 1000°C are – 49.0 kJ/mol and -127.2 kJ/mol, respectively use these to predict weather H2 (g) will reduce CdS(s) to metallic Cd at this temperature ∆G is equal to:

A) -78.2 kJ/mol and H2 reduces CdS

B) 35.66 kJ/mol and H2 reduces CdS
