Consider the reaction: ab as the reaction proceeds, the concentration of a drops from 0.625 m to 0.100 min 11.6 seconds. what is the average rate of the reaction (in m/s) during this time?

0.045 M/s

Explanation:

Given:

Initial concentration of A = 0.625 M

Final concentration of A = 0.100 M

Total time taken for the change of concentration = 11.6 seconds

The average rate of reaction is calculated as:

=

on substituting the respective values, we get

=

or

The average rate of reaction = 0.045 M/s
