Toward I2 (s) Production - apex

Zoie Hansen · Answer 2

Let's find the Gibb's free energy for this reaction. The formula is:

G = H - TS

G = (62.4 kJ/mol) - (298 K) (0.145 kJ/mol·K)

G = + 19.19 kJ

Now, the sign of G is a criterion for spontaneity. If its sign is -, it means the reaction is spontaneous. Since we got a positive sign, that means the reaction is non-spontaneous. Consequently, the reverse of this reaction would make it negative and spontaneous. Therefore, the favorable reaction is the reverse reaction.
