Calculate the pressure of o2

Assignment Help Chemistry
Reference no: EM13537824

Calculate the pressure of O2 (in atm) over a sample of NiO at 25 degrees Celcius if the delta G standard = 212 kJ/mol for the reaction: NiO(s)<-->Ni(s)+(1/2)O2(g)

The equilibrium constant Kp for the reaction CO(g)+Cl2(g) <--> COCl2(g) is 5.62x10^35 at 25 degrees Celcius. Calculate delta G of formation for COCl2 at 25 degrees Celcius.

The answers I'm getting seem really, really off ( like 4.73x10^-75 atm for the first one?!)
