You can skip questions if you would Problem : Describe the difference between the rate constant and the rate of a reaction. The rate of a reaction is the change in concentration with respect to time of a product. The rate equals the rate constant times the concentrations of the reactants raised to their orders. Time-saving chemistry video providing practice with problems involving reaction rate laws and reaction mechanisms. Reaction rate laws are equations which allow us to predict the rate of a reaction using the concentrations of the reactants.
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. A reversible chemical process is considered in equilibrium when the rate of the forward reaction equals the rate of the reverse reaction. The ratio of these reaction rates is called the equilibrium constant.Test your knowledge about equilibrium constants and their use with this ten question equilibrium constant practice.
