The rate of disappearance of HCl was measured for the following reaction:
CH3OH(aq) + HCI(aq) --→ CH3CI(aq) + H2O(I)
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 reaction, in , for the time
interval between each measurement. (b) Calculate the average
rate of reaction for the entire time for the data from
to .
(c) Graph [HCl] versus time and determine the instantaneous
rates in and at and .
