What is the average reaction rate with respect to each component (i.e., average -A[A]/At, average -A[B]/At, and average A[ABJ/A)?

(to be completed by 2 pair of students) Comparisons (Work together with the other pair in your group of 4 to answer the following questions) When is the rate the greatest? When is the rate the slowest? Write the balanced chemical equation. Using the initial rate (rate from Flask I to Flask II), does the -A[A] A[B]A[AB.]? At 2 At At Using the average rate (rate from Flask I to Flask VI), does the -A[A] At How could you get the reaction to go faster if the reaction is 1st-order in A and 2nd-order in B? Which would change the rate more, increasing [A] or [B]? 1 A[B] A[AB.]? 2 At At Besides changing [A] or [B], what else would increase the reaction rate? 34
