Determine whether or not the following gas phase reaction is spontaneous at 25 degrees Celsius. CH4(g)+N2(g)=HCN(g)+NH3(g)

Expert Solution

For spontaneous process, we require dG < 0

so

claculate dG

dG = Gproducts - Greactants

dG = (HCN + NH3) - (CH4 + N2)

dG = (124.7+-16.4) - (-74.2 + 0)

dG = 182.5 kJ/mol

since this is possitive, this will not occur at T = 25°C and P = 1 atm
