_ are units of rate of reaction.
Correct answer: C. mol dm-3 sec-1
- A. mol dm3 sec-1
- B. mol dm3 minute-1
- C. mol dm-3 sec-1
- D. mol dm3 hour-1
Explanation
The correct answer is mol dm-3 sec-1. The rate of reaction is the change in concentration of a reactant or product over time. The units of rate of reaction are moles per cubic decimeter per second (mol dm-3 sec-1). This means that the rate of reaction is the number of moles of reactant or product that are converted per cubic decimeter of solution per second.

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.
