Negative order reactions are reactions where an increase in the concentration of a reactant or product means a decrease in the rate. Take as an example the conversion of ozone to oxygen: 2O3(g) -> 3O2(g). Tap to unmute. If playback doesn't begin shortly, try restarting your device. You're signed out.
