Reaction rates
Webreaction rate is the concentration of the reactants An increase in concentration means an increase in the number of particles in the reaction. This results in an increase in the … 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.
