Calculate of the average rate of the reaction : А + В = С, if after 10 seconds, the concentration of substance A was 0,2 mol/lit, and of after 40 seconds , the concentration of this substance was of 0,02 mol/lit.

To calculate the average rate of the reaction, we need to use the formula:
Average rate = (change in concentration of A) / (time interval)
In this case, the change in concentration of A is:
0.2 mol/lit — 0.02 mol/lit = 0.18 mol/lit
And the time interval is:
40 seconds — 10 seconds = 30 seconds
So, the average rate of the reaction is:
Average rate = (0.18 mol/lit) / (30 seconds) = 0.006 mol/lit/sec
Therefore, the average rate of the reaction is 0.006 mol/lit/sec.
