The unit of rate of reaction is:
Correct answer: C. Mole(dm-3) sec -1
- A. Mole (dm3) sec
- B. Mole (dm3) sec-1
- C. Mole(dm-3) sec -1
- D. Mole(dm3)sec-2
- E. Mole (dm3)-1 sec -2
Explanation
Reaction rates are usually expressed as the concentration of reactant consumed or the concentration of product formed per unit time. The units are thus moles per decimeter cube per unit time [Mole (dm-3)'sec -1 ].

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.
