Rate of reaction has?
Correct answer: D. Unit of moles/dm3s-1
- A. No units
- B. Unit of moles/dm3
- C. Unit of moles/litre
- D. Unit of moles/dm3s-1
Explanation
The formula for the rate of reaction is concentration/time. Unit for concentration is mol/dm3 and the unit for time is s. Hence the unit of the rate will be mol/dm3s-1.

About Rate of Reaction
Reaction rate measures the change in concentration of a reactant or product per unit time. Questions connect rate with concentration, temperature, pressure, surface area, catalysts and nature of reactants, and may involve rate laws, reaction order, activation energy and collision theory. Rate describes speed, whereas equilibrium describes the final balance of opposing reactions.
