Question
Iodine is not very soluble in water, but it dissolves readily in a solution containing iodide ions by the following reaction: I₂ (aq) + I¯ (aq) → 13(aq) The following graph shows the results of a study of the temperature dependence of AG for this reaction. (The solid line is a best fit to the actual data points.) Notice that the quantity on the y axis is AG /T, not just AG. Additional data relevant to this reaction are also given in the table that follows the graph.
