rate ofreaction independent to concentration reaction is
Correct answer: B. 1 order reaction
- A. zero order reaction
- B. 1 order reaction
- C. 2 order reaction
- D. 3 order reaction
Explanation
the first order reaction does not dependent on concentration because as only one reactant is involved in rate determining step.The rate constant (k) is a constant and depends only on the temperature, not on the concentration.

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.
