Explanation / Answer

Given: Delta H = 120.5 kJ/mol

Delta S = 758.2 J / (K.mol)

Delta G

We know

Delta G = Delta H – T delta S

T = 298 K

Lets plug the value and get the answer

= 120.5 x 103 J / mol – 298 K x 758.2 J/ K

=-105443.6 J/ mol

= -105.443 kJ/mol

Since the value of Delta G is negative so the reaction is spontaneous.
