Explanation / Answer

3C2H2(g) ----> C6H6(l)

?Sorxn = ?S0products – ?S0reactants

?Sorxn = [( ?S0C6H6(l) ]- [( 3 x ?S0C2H2(g) )]

= [173.26]-[200.8] J/(mol-K)

= -27.54 J/(mol-K)

?Gorxn = ?G0products – ?G0reactants

?Gorxn = [( ?G0C6H6(l) ]- [( 3 x ?G0C2H2(g) )]

= [124.35]-[(3X209.2] kJ/mol

= -503.25 kJ/mol-K

Since ?Gorxn is negative the reaction is spontaneous so forward reaction takes place
