Curves A, B, and C in Figure P15-4A show the variations in reaction rate for three different reactions catalyzed by solid catalyst pellets. What can you say about each reaction?

Temperature dependence of three reactions. In the graph, the vertical axis represents natural log of (negative r prime subscript A) and the horizontal axis represents 1 over T. The reaction rate of A decreases gradually until a point and falls rapidly, reaction rate of B decreases gradually, and reaction rate of C decreases rapidly. While, B and C show a linear decrease, A shows a non-linear decrease.
