For which of the following order of the reaction, rate of reaction is inversely proportional to the concentration reaction?
Correct answer: B. 2nd order reaction
- A. 1st order reaction
- B. 2nd order reaction
- C. Negative order of reaction
- D. Zero order of reaction
Explanation
The rate of reaction is inversely proportional to the concentration of the reactant in a second-order reaction (option b). In first-order reactions, the rate is directly proportional to the concentration, while in zero-order reactions, the rate is independent of the concentration. Negative order of reaction is not a recognized concept in chemical kinetics.The rate of a second-order reaction is inversely proportional to the initial concentration of reactants. This means that if the concentration of a reactant is doubled, the rate of the reaction will also double. The half-life of a second-order reaction is also inversely proportional to the initial concentration of the reactant.

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.
