• A. The rate of a reaction can be expressed in terms of the amount of any one of the reactants being consumed in unit time.
• B. The rate of a reaction can be expressed in terms of the amount of any one of the products formed within a specific period of time.
• C. The rate of a reaction does not depends on the reactants beings consumed in unit time.
• D. The rate of a reaction does not depends on the products formed within a specific period of time.

Answer 1

Answer: (A), (B)

The correct options are
A

The rate of a reaction can be expressed in terms of the amount of any one of the reactants being consumed in unit time.

B

The rate of a reaction can be expressed in terms of the amount of any one of the products formed within a specific period of time.

The rate of a reaction can be expressed in terms of the amount of any one of the reactants being consumed in unit time. It can also be expressed in terms of the amount of any one of the products formed within a specific period of time.

$\text{Rate of reaction}=\frac{\text{Amount of reactant used}}{\text{Time taken for the consumption of the reactant}}$ (in terms of concentration of reactants)

$\text{Rate of reaction}=\frac{\text{Amount of product formed}}{\text{Time taken for the formation of the product}}$ (in terms of concentration of products)
