In 12 minutes, the concentration of one of the reagents changed from 0.44 to 0.20 mol / L. Calculate the average reaction rate over a given period of time.
The term reaction rate is understood as the change in the concentration of the reagent per unit time.
Let us find the change in concentration: 0.44 – 0.2 = 0.24 mol / l.
Time. for which this change occurred 12 minutes.
0.24 / 12 = 0.02 mol / L * min.
Answer: the average reaction rate is 0.02 mol / l * min.
