Rate= k[NO][O3] the order of this reaction is:
Correct answer: A. 2
- A. 2
- B. 0
- C. 1
- D. 3
Explanation
The given chemical reaction is: Rate = k[NO][O3] The order of a chemical reaction with respect to a specific reactant is determined by the exponent (known as the reaction order) to which the concentration of that reactant is raised in the rate equation. In the given rate equation, we have: Rate = k[NO][O3] The reaction order with respect to NO is 1 (since the concentration of NO is raised to the power of 1), and the reaction order with respect to O3 is also 1. The overall reaction order is the sum of the individual reaction orders: Overall reaction order = 1 + 1 = 2 Thus, the overall order of this reaction is 2. It is a second-order reaction with respect to the concentrations of both NO and O3.

About Order of Reaction
Reaction order shows how the rate depends on the concentration of each reactant, as expressed in the rate law. Coverage includes zero, first and second-order reactions, integrated rate equations, half-life, units of rate constants and the distinction between overall order and molecularity.
