Web- A mechanism is the sequence of elementary steps by which a reaction proceeds. So if we look at this reaction here we have nitrogen dioxide plus carbon monoxide giving us nitric oxide and carbon dioxide. Our two reactants don't go to our products in one step. There's a sequence of elementary steps by which the reaction proceeds. WebReaction mechanisms and orders of reaction. The examples we use at this level are the very simple ones where the orders of reaction with respect to the various substances taking … WebProposed mechanism: A + B->AB (slow) A + 2B->AB2 (Fast) AB + AB2->A2B3 (Fast) Write the rate law for this reaction. (b) Ozone reacts with nitrogen dioxide to produce dinitrogen pentoxide and oxygen: O3 (g) + 2 NO2->N2O5 (g) + O2 (g) The reaction is believed to occur on two steps: O3 (g) + NO2->NO3 (g) + O2 (g) NO3 (g) + NO2->N2O5 lautapelit lapsille
