Question

The rate of a reaction is expressed in the units
(a) L mol⁻¹ t⁻¹
(b) mol dm⁻³ t⁻¹
(c) Ms
(d) M⁻¹s⁻¹

Answer 1

Explanation:

Sandy is a correct answer

Answer 2

Answer:

(b) mol dm⁻³ t⁻¹

Explanation:

The rate of reaction can be expressed in the units mol dm⁻³ t⁻¹. We define the rate of reaction as the change in concentration of the reacting agent in the given interval of time. The change in concentration of the reacting agent is nothing but the difference of final concentration when we get the product and the initial concentration when the reaction just started.
