Chemical Reaction RatesA series of free High School Chemistry Video Lessons from Brightstorm.
Reaction Rate Laws Reaction rate laws give an equation for finding the rate of a reaction using the concentration of the reactants and the stoichiometric coefficients. For the chemical equationaA +bB => C the reaction rate law is reaction rate = k[A]^a [B]^b where k is a constant.
Reaction Rate Problems In class, you may often be asked to solve different types of reaction rate problems. When solving reaction rate problems, it is important to remember the reaction rate laws and the basics of balancing equations.
Energy Diagrams Energy diagrams depict the reaction progress versus energy. For exothermic reactions, the reactants are drawn above the products because their energy is greater. However, for endothermic reactions, the reactants are drawn below the products. Catalysts lower activation energy, so they decrease the size of the hump within the diagram itself.
