Identify each of the following elementary reactions as unimolecular, bimolecular, or
termolecular, and write the rate expression.
Reaction
(a) OH + HCI →→ H₂O + CI
(b) HO₂NO₂ - HO₂ + NO₂

Expert Solution

Step 1

Given ->

Step1-> NO₂ + CO ----> ONOCO

Step2-> ONOCO -----> NO + CO₂

-> Molecularity is the number of molecules that come together to reacts in an elementary reaction and it is equal to sum of stoichiometry coefficient of reactants in elementary reaction.

-> I a general equation aA + bB ----> product

Rate law expression is->

Rate = k[A]^a[B]^b
