Because the reaction is third-order, the sum of the exponents in the rate law must be equal to 3. Therefore, the rate law is defined as follows: rate – k[A][B] 2. Reactant A has no exponent because its concentration is directly proportional to the rate.
The third derivative is found by evaluating the first derivative three times: at n, at n+1/2, and at n+1. Put this form of the third derivative into the previous equation and rearrange to get

Reaction order. The order of a rate law is the sum of the exponents in its concentration terms. For the N 2 O 5 decomposition with the rate law k[N 2 O 5], this exponent is 1 (and thus is not explicitly shown); this reaction is therefore a first order reaction. We can also say that the reaction is “first order in N 2 O 5 “. For more complicated rate laws, we can speak of the overall reaction
Chemical reaction engineering is the synthesis of all these factors with the aim of properly designing a chemical reactor.
