Unit for rate of reaction is?
Correct answer: D. moles/dm3 s-1
- A. Mole/ litre
- B. Moles/ gram
- C. Moles/ Second
- D. moles/dm3 s-1
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 litre per unit time, written as M/s, M/min, or M/h. (M=moldm-3)

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.
