To find the average rate of reaction at 20 seconds, read off the volume of product for this time To find out the average rate of reaction at 20 seconds: ...

The results recorded here show that the reaction had finished by four minutes, as no more gas was produced after that. The mean rate of reaction = 50 ÷ 4 = 12.5 cm 3 /min However, the rate decreased ...
