Use the reaction i2(s) i2(g), h = 62.4 kj/mol, s = 0.145 kj/(molk), for question 10. which direction of the reaction is favored at 298 k (room temperature)?

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.
