Question- A. Calculate ?G for the formation of ethylene (C2H4) from carbon and hydrogen at 25 ?C when the partial pressures are 200atm H2 and 0.50atm C2H4.
2 C(s)+2H2(g)?C2H4(g) ?G? = 68.1 kJ B. Is the reaction spontaneous in the forward or the reverse direction?
I am in urgent need of solution of above problem with complete explanation
