Chemical equilibrium in solution essay chemical equilibrium in solution 2/5/13 jim jacobs (partner: jessica janiga) abstract the purpose of this experiment was to determine the equilibrium established between iodine species [i3-, i2, and i-] dissolved in an aqueous ki solution. The chemical equilibria are classified into two types: 1) homogeneous equilibrium: a chemical equilibrium is said to be homogeneous if all the substances (reactants and products) at equilibrium are in the same phase. - chemical equilibrium is the point at which the rate of the forward reaction is equal to the rate of the reverse reactions - at that point, the concentrations of all species are constant. In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change.
In a chemical reaction, chemical equilibrium is defined as the state where there is no further change in the concentration of the reactants or products chemical equilibrium is also called as a steady state reaction. In a chemical process, chemical is a state in which cocentration of reactants and the concentration of products does not change overtime ie when the forward reaction proceeds at the same rate as backward reaction and it exists in dynamic equilibrium.
