In the rate equation, Rate=k[A]ᵃ[B]ᵇ, the sum of terms a and b is called as_?
Correct answer: A. Overall order of reaction
- A. Overall order of reaction
- B. Order of reaction with respect to A
- C. All of these
- D. Order of reaction with respect to B
Explanation
The overall order of the reaction is determined by adding the individual orders which in the given equation are given by 'a' and 'b' where a is the order of reaction with respect to A and b is the order of reaction with respect to B. Thus a + b is the overall order of the reaction.

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.
