Consider the reaction. A + B → C + D (i) If the reaction is endothermic and spontaneous in the direction indicated, comment on the sign of ΔG and ΔS. (ii) If the reaction is exothermic and spontaneous in the direction indicated, can you comment on the sign of G and S? (iii) If the reaction is exothermic and spontaneous only in the direction opposite to the indicated, comment on the sign of AG and AS for the direction indicated in the equation. |
