Question

The formula to calculate the rate of the reaction in terms of concentration of reactants is

• A. $\text{Rate of reaction}=\frac{\text{Amount of reactant used}}{\text{Time taken for the consumption of the reactant}}$
• B. $\text{Rate of reaction = Amount of reactant used}\times \text{Time taken for the consumption of the reactant}$
• C. $\text{Rate of reaction = Amount of reactant used + Time taken for the consumption of the reactant}$
• D. $\text{Rate of reaction = Amount of reactant used - Time taken for the consumption of the reactant}$

Answer 1

The correct option is A

$\text{Rate of reaction}=\frac{\text{Amount of reactant used}}{\text{Time taken for the consumption of the reactant}}$

The rate of reaction determines the speed by which a chemical reaction proceeds. It can be calculated using the formulas:

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