Decomposition reaction rate law
WebNov 13, 2024 · The relation between the rate of a reaction and the concentrations of reactants is expressed by its rate law. For example, the rate of the gas-phase decomposition of dinitrogen pentoxide (17.1.9) 2 N 2 O 5 → 4 N O 2 + O 2 has been … WebThe decomposition of HI is a second-order reaction because the rate of reaction depends on the concentration of HI raised to the second power. Rate = k (HI) 2 When the rate of a reaction depends on more than one …

WebJul 18, 2024 · The reaction scheme is an overall one whereas the rate equation refers to a particular multi-step reaction. Two examples are given below: Ozone can be destroyed by UV light in the $240$ to $\pu{320 nm}$ region with the scheme $(\ce{M}$ is an inert gas needed to take away excess energy): WebThe predicted rate law for the overall reaction is therefore \text {rate} = k [\ce {NO2}]^2 rate = k[NOX 2]2 This rate law is in agreement with the experimentally-determined rate law we saw earlier, so the mechanism also meets the second condition (check!).
