2/4/18 – Kinetics Average Rate and Reaction Stoichiometry Reaction Rate: The speed at which a reaction progresses; expressed as a ratio of change in concentration over time. - Reaction rate is defined using the negative of the change in a reactant concentration over the change in time. Ex: For the reaction A 2B, Rate = -Δ[A]/Δt Average Reaction Rate: Obtained from the change in concentration of a reactant or product over a defined time interval. Ex: Rate = Δ[B]/Δt *If a product/appearing in the reaction, the equation is positive. *If a reactant/disappearing in the reaction, the equation is negative. Instantaneous Rate: The rate of reaction at a given point in time, equal to the slope of a line tangent to the concentration-time curve. Recall th
