Question

8. What is the unit of rate or velocity of a reaction​

Answer 1

Answer:

The units for rate of reaction is mol dm-³ s-¹. Rate means rate of change of concentration of reactant per unit time.

Answer 2

Answer: Moles per liter per unit time is the unit of rate or velocity of a reaction.

Explanation:

Concept:

• The concentration of reactant consumed or the concentration of product created per unit time are the two ways that reaction rates are typically stated. Thus, the measurements are in moles per litre per unit of time, denoted as M/s, M/min, or M/h.
• Chemists start a reaction, measure the reactant or product concentration at various points as the reaction advances, and maybe plot the concentration as a function of time on a graph.
• Then they calculate the change in concentration per unit time.
• So the units for measuring the rate of reaction is Moles per liter per unit time.
