Problem 2 (15 points). If you have two surface reactions: 1. AB 2. AC where reaction 1 is first order, and reaction 2 is second order, what can you say qualitatively about 1 compared to 2 if both reactions are internally mass transfer limited? Explain your answer. What if there was a third reaction AD that had a reaction order of negative one? Hint: Think about the definition of the effectiveness factor (i.e., not the equation that we derived). If the reaction order was zero, would this definition of the internal effectiveness factor make sense? Why or why not
