Advanced Level Chemistry Practical Made Simpler

It is found by expert that Reagents are brought together so as to undergo chemical Rxn the conversion of Rxts to products is often incomplete no matter how long the Rxn is allowed to continue. In the initial state the Rxts are present at a definite concentration. As the Rxn proceeds the concentrations of Rxts decrease. Sooner or later however they level off and become constant in other words of all Rxts to products remain constant. A state is thus established in which to concentration to longer change. This state is known as the state of chemical equation.
