The table shows the concentration of a reactant in the reaction mixture over a period of time.


Reactant Concentration
Time Concentration
0 s 1.8 M
210 s 1.2 M
450 s 0.8 M
580 s 0.6 M
720 s 0.4 M


What is the average rate of the reaction over the first 580 seconds?
1.6 × 10−3
1.9 × 10−3
2.0 × 10−3
2.2 × 10−3

The average rate of reaction for the first 580 seconds is 2.0 × 10−3 M/s.

What is average rate of reaction?

The average rate is defined as the ratio of the change in concentration to the time taken. We are required here to find the average rate of the reaction over the first 580 seconds.

Hence, we have;

average rate = 1.8 M - 0.6 M/580 s - 0 s = 1.2 M/580 s  = 2.0 × 10−3 M/s

Hence, the average rate of reaction for the first 580 seconds is 2.0 × 10−3 M/s.
