C2H4(g) + H2(g) ---> C2H6(g)

dH^orxn = dH^oproducts - dH^oreactants

Â Â Â Â Â Â Â Â Â Â Â = (-84.68) - (52.25)

Â Â Â Â Â Â Â Â Â Â Â = -136.93 kJ/mol

dS^orxn = dS^oproducts - dG^oreactants

Â Â Â Â Â Â Â Â Â Â Â = (229.6) - (219.45 + 130.684)

Â Â Â Â Â Â Â Â Â Â Â = -120.534 J/K.mol

dG^orxn = -136.93 - (298 x -0.120534)

Â Â Â Â Â Â Â Â Â Â Â Â = -95.011 kJ/mol

C3H6(g) + H2(g) ---> C3H8(g)

dH^orxn = dH^oproducts - dH^oreactants

Â Â Â Â Â Â Â Â Â Â Â = (-104.5) - (20.2)

Â Â Â Â Â Â Â Â Â Â Â = -124.7 kJ/mol

dS^orxn = dS^oproducts - dG^oreactants

Â Â Â Â Â Â Â Â Â Â Â = (269.9) - (266.9 + 130.684)

Â Â Â Â Â Â Â Â Â Â Â = -127.684 J/K.mol

dG^orxn = -124.7 - (298 x -0.127684)

Â Â Â Â Â Â Â Â Â Â Â Â = -86.65 kJ/mol
