Question

The rate expression for a reaction was found to be?

Answer 1

The rate expression for a reaction was found to be an equation that describes the relationship between the rate of the reaction and the concentrations of reactants.

Step-by-step explanation:

The rate expression in a chemical reaction illustrates how the rate of the reaction is influenced by the concentrations of the reactants. It is typically determined experimentally and may involve various orders with respect to each reactant.

For instance, in a simple reaction like aA + bB
`\rightarrow` cC + dD, the rate expression might be represented as
`Rate = k[A]^m[B]^n\)` where k is the rate constant, m and n are the reaction orders with respect to reactants A and B respectively, and A and B represent their concentrations.

These exponents m and n might not necessarily match the stoichiometric coefficients a and b of the balanced equation; they are determined through experimentation. The rate expression is crucial as it provides insights into the reaction's mechanism, allowing for a better understanding of how the reactants interact to form products.
