Concentration of Reactant and Reaction Rates

Vocabulary flashcards covering rate expressions, balance coefficients, and order calculations based on Chapters 1 and 2.

Stoichiometric Factors

Another name for balance coefficients in a chemical reaction required when measuring reaction rates.

Balance Coefficients

The stoichiometric numbers in a balanced reaction equation used in rate expressions.

Rate of a Reactant

The change in concentration of a chosen reactant over an amount of time, preceded by a fraction with a negative sign to represent its decrease over time.

Rate of a Product

The change in concentration over time with a positive sign, indicating that the substance is being created over time.

Zero Order

A reaction order classification where rate behavior is demonstrated regardless of whether starting reactant concentration begins at $0.2$ or $0.4$.

Trial 2 Concentration

The specific concentration value of $0.05$ used for trial 2 in calculating rate law exponents.

Trial 3 Concentration

The specific concentration value of $0.1$ used for trial 3 in calculating rate law exponents.
