C2H2 (g) + 4Cl2(g) ----------> 2CCl4(l)+ H2(g)
Gibbs free energy changes at standard conditions
C2H2(g) : 209 Kj/mole CCl4 (l)= -65.3 Kj/Mole. Free energy changes for H2 and Cl2=0
Gibbs free energy change= Gibbs free energy of products- Gibbs free energy of reactants=
2* Free enerrgy chagne of CCL4+1* Free energy change of Hydrogen- {1* Free energy change of C2H2 + 4* Free energy change of Cl2)
=2*-65.3+0 -209=-339.6 Kj
