Reaction rates

WebCompare the nature of reactions with first-order and second-order rates. Given a set of data about a reaction, calculate the reaction rate, activation energy, reaction order, and/or rate constant, and derive a general expression for the concentration over time. Sketch an energy-level diagram for a reaction, labeling key features.
