Webb2 okt. 2024 · A non elementary reaction is one that does not take place in a single reactive encounter. In other words, the reaction is comprised of many steps. The overall reaction equation is the sum of all the reaction steps after all intermediates have been cancelled out. The rate law is obtained from the slowest step in the reaction sequence. Webb15 mars 2024 · Below is the general equation: 2O 3 ↔ 3O 2. Under experimental conditions, scientists have determined that the rate law equation for this reaction is: Rate = k [O 3] 2 [O 2] -1.
