which of the following rate law is third order? plz answer
Answers
The rate expression is r=k[A]²[B].
The reaction is second order in A and first order in B.
The overall order of the reaction is 2+1=3.
From the given rate law expression, the mechanism cannot be determined. Hence, the slowest step of the reaction cannot be determined.
Because two units of concentration already are present in a second-order reaction, the rate constant requires inverse time plus reverse unit of concentrations, L mol-1 s-1.
The total of the exponent of a rate law's concentration terms determines its order. After determining the rate constant of a reaction, the same law can be utilised to better understand the content of the reaction mixture. To determine out the order of each reaction from a table, you should mathematically evaluate how changes in molarities of reactants effect the reaction rate. Then, to obtain the particular rate constant, fill in values for the rate of the reaction and reactant concentrations.
