Relating Rates at Which Products Appear and Reactants Disappear

(a) How is the rate at which ozone disappears related to the rate at which oxygen appears in the

reaction \(2 O_{3}(g) \rightarrow 3 O_{2}(g)\)?

(b) If the rate at which \(O_{2}\) appears, \(\Delta\left[\mathrm{O}_{2}\right] / \Delta t\), is \(6.0 \times 10^{-5} M / s\) at a particular instant, at what

rate is O3 disappearing at this same time, \(-\Delta\left[O_{3}\right] / \Delta t\)?

If the rate of decomposition of \(\mathrm{N}_{2} \mathrm{O}_{5}\) in the reaction \(2 N_{2} O_{5}(g)+O_{2}(g)\) at a particular instant is \(\text { 4. } 2 \times 10^{-7} M / s\), what is the rate of appearance of (a) \(\mathrm{NO}_{2}\) and (b) \(O_{2}\) at that instant?
