Quizplus · Accepted Answer

The reaction appears to have reached completion in drawing (d), which is 7 minutes after the start of the reaction. The previous drawings show intermediate stages where there are still unreacted A molecules present. Therefore, it can be inferred that the reaction takes at least 7 minutes to complete.
