APFIVE A differential equation modeling ozone depletion is given by $$\frac{dO}{dt}=-k \cdot O(t) \cdot H$$, where $H$ is a constant halocarbon concentration. This equation yields a solution that shows an exponential decay in ozone concentration. Which of the following conclusions is best supported by this model?
The exponential solution of the differential equation indicates that reducing halocarbon emissions can have a long-term positive effect on preserving ozone levels by slowing down the rate of ozone depletion.
The evidence suggests that ozone depletion is entirely independent of halocarbon concentrations, implying that changes in H would have no effect on ozone levels.
The derived exponential decay indicates that halocarbons actually increase ozone concentrations, contradicting expected outcomes of ozone chemistry.
The model demonstrates that any reduction in ozone concentration is immediately reversed with even a small decrease in halocarbon levels, implying an instantaneous recovery.
