Figure 2

A diagram of the rate of chemical reactions at different acetone concentrations. The squares and circles represent the introduction of target gas and air into the test environment, respectively. The red line represents the rate of consumption oxygen ions. The blue and green lines indicate the rate of generation oxygen ion in the presence/absence of competing reactions.
