Document Summary
18. 1 equilibrium: a state of dynamic balance. This is when the rate of the production of the products is the rate of the depletion of the reactants. Sometimes, standard conditions (298 k, 1 atmosphere) do not produce a product that is fast enough, so the temperature must be raised and the reaction must be conducted at atmospheres higher than one. However most reactions do not go to completion. These are known as reversible reactions and are depicted by double arrows. Reactants at max concentration, forward rate at maximum, reverse rate at zero. Reactant concentration lower, forward rate slower, some reverse reaction. Forward and reverse rates equal no further concentration changes. If the rate of the product being is produced is the same as the rate of the reactant being depleted. Not necessarily do the concentrations or amount of substance have to be equal, just the rate.
