Explanation / Answer

Given H = 120.5 kJ/mol
     S = 758.2 J/(mol-K)
        = 0.7582 kJ/(mol-K)
Temperature , T = 298 K
We know that G = H - T S
                 = 120.5 - ( 298 x 0.7582 )
                  = -105.4 kJ/mol
Therefore G= -105.4kJ/mol
Since the value of G is -ve the reaction is spontaneous reaction.
