The rate of disappearance of HCl was measured for the following reaction: CH;OH(aq) + HCI(aq)CH;CI(aq) + H20() The following data were collected: Time (min) [HCI] (M) 0.0 1.85 54.0 1.58 107.0 1.36 215.0 1.02 430.0 0.580 a. Calculate the average rate of the reaction in M/min, for the time interval betwe each measurement (similar to the rate data in Table 1). b. Calculate the average rate between t = 54 min and t = 215.0 min and between t 107.0 min and t = 430.0 min. Which is greater? Explain the difference between t two rates. c. Using the graph of [HCI] vs time shown Annex 1 below, estimate the instantaned rate at t =75.0 minute and t 250. Min. %3D

a. Calculate the average rate of the reaction in M/min, for the time interval between
each measurement (similar to the rate data in Table 1).
b. Calculate the average rate between t = 54 min and t = 215.0 min and between t =
107.0 min and t = 430.0 min. Which is greater? Explain the difference between the
two rates.
c. Using the graph of [HCI] vs time shown Annex 1 below, estimate the instantaneous
rate at t =75.0 minute and t = 250. Min.
