This is one of the steps in synthesising sulphuric acid: You have a mixture of gaseous sulphur dioxide and oxygen, from which you can react to form sulphur trioxide.

To give you more insight about how this equation works in practice, we created this example. However the constant may be influenced by: The constant doesn't depend on initial concentrations of the reactants and products, as the same ratio will always be reached after a certain period of time. Where and are the molar concentrations of the reactants, and and are the molar concentrations of the products.Ĭalculating the value of the equilibrium constant for a reaction is helpful when determining the amount of each substance formed at equilibrium as a ratio of each other. With this tool, you can calculate the value of an equilibrium constant for a reaction while learning how to calculate the equilibrium constant with ease!īelow you can find the reversible reaction and equilibrium constant equations: To determine state of this equilibrium, the reaction quotient should remain constant. At this point the reaction is considered stable. After a certain amount of time an equilibrium is formed, meaning that the rate of reactants being turned into products is the same as the rate of products being turned back into reactants. This equilibrium constant calculator will help you understand reversible chemical reactions, which are reactions in which both the forward and backward reaction are occurring simultaneously.
