The rate constant of a reaction is 3 x 10^-3 mol dm-3 sec-1. The order of reaction is
Correct answer: D. 0
- A. 1
- B. 3
- C. 2
- D. 0
Explanation
The rate constant of a reaction has the same units as the rate of reaction when the order of the reaction is zero. In this case, the rate constant has units of mol dm^-3 s^-1, which is the same as the units of the rate of reaction for a zero-order reaction.

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.
