Part I - Reaction Rates Defined 1. Consider the following data for the hypothetical reaction 2A(=> 3B () Time, min. Moles of A 0 .100 40. .067 80. .045 120. .030 160. .020 a. Calculate the number of moles of B at 40. minutes, then at 120 minutes. b. Is the reaction rate increasing, decreasing, not changing, or something else as the reaction proceeds? c. Describe how to determine the instantaneous reaction rate at 75 minutes
