The order of reaction for which half-life is inversly proportional to the concentration of reactant is:
Correct answer: A. Second order
- A. Second order
- B. Zero order
- C. First order
- D. Third order
Explanation
In a second-order reaction, the relationship between half-life and concentration is such that the half-life is inversely proportional to the concentration of the reactant raised to the power of one. As the concentration decreases due to the reaction progressing, the half-life increases proportionally. Therefore, higher concentrations result in shorter half-lives, demonstrating an inverse relationship between concentration and half-life.

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.
