In a zero-order reaction, the rate is independent of:
Correct answer: B. The concentration of reactants.
- A. The temperature of the reaction
- B. The concentration of reactants.
- C. Concentration of products
- D. Catalyst used
Explanation
Zero order reactions are those in which the concentration of the reactants does not change over time and the concentration rates remain constant. Unlike the other orders of reaction, it has a rate that is independent of the reactant concentrations. This is why increasing or decreasing the concentration of the reacting species has no effect on the reaction rate.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
