What is the overall reaction order for the reaction that has the rate law: Rate = k[F₂]²[NO]?

Question

Quizplus · Accepted Answer

The overall reaction order is determined by adding the exponents in the rate law. In this case, the rate law is Rate = k[F₂]²[NO], which simplifies to Rate = k[A][B]. Each reactant concentration is raised to the first power, so the overall reaction order is 1 + 1 = 2, indicating a second-order reaction. However, the correct interpretation of the provided rate law seems to be obscured by formatting issues. Assuming the intended rate law is Rate = k[A]^1[B]^1, the answer would indeed be second order. If the rate law was intended to be Rate = k[A][B][C], with each reactant concentration raised to the first power, then the overall reaction order would be 1 + 1 + 1 = 3, indicating a third-order reaction. Given the potential confusion from the formatting, the correct interpretation based on standard notation would be third order if three distinct reactants are implied.
