Rate laws and Order of a Reaction - Purdue University

WebIn a chemical equation, a rate law connects the concentration of a reactant to the reaction rate. It's represented as rate = k [reactant1] [reactant2], with k being a reaction-specific rate constant. The reactant concentrations can be increased by an exponent (usually first or second power). Formula: Rate = k [A] m [B] n where: k = rate constant WebReaction Order The sum of exponents in a rate law equation. Independent Rate of Reaction The relationship between the amount of reactant consumed and time is linear. Rate Law An expression of the dependence of the reaction rate upon reactant concentrations.
