Consider the figure below which shows ΔG° for a chemical process plotted against absolute temperature. From this plot, it is reasonable to conclude that:

Question

From the plot, we see that ΔG° decreases with increasing temperature, which implies that ΔH° > 0 (since the reaction becomes less favorable at low temperatures) and ΔS° < 0 (since the reaction becomes more favorable at high temperatures, and that typically corresponds to an increase in disorder). Therefore, the correct choice is B.
