Chemical Reaction Rates: Exploring the Relationship Between Products and Reactants

How are the rate of appearance of product and the rate of disappearance of reactant related?

Group of answer choices:

A. They are inversely proportional

B. They are related by reaction stoichiometry

C. Both: inversely proportional and reaction stoichiometry

Final answer:

The rate of appearance of a product and the rate of disappearance of a reactant in a chemical reaction are related by reaction stoichiometry.

Explanation:

The rate of appearance of a product and the rate of disappearance of a reactant in a chemical reaction are closely related to each other. They follow the principle of reaction stoichiometry. In a chemical reaction, it can be expressed either in terms of the decrease in the amount of a reactant or the increase in the amount of a product per unit time. These rate expressions are derived from the stoichiometric coefficients of the reaction. Essentially, as the reactant in a reaction dissipates, the product simultaneously appears. The speed at which this transformation occurs is directly related by the reaction's stoichiometry - that is, the proportional relationship defined by the reaction's balanced chemical equation.
