Explain and distinguish between the following:
A. chemical reaction equilibrium
B. chemical equilibrium
C. osmotic equilibrium
A. Chemical reaction equilibrium is achieved in reversible reactions when the rate of the forward reaction equals the rate of the reverse reaction. At this state there is no net change in the concentration of reactants and products in
the system. This does not mean that concentrations are equal.
B. Chemical equilibrium occurs when the concentration of a particular solute in one location equals that in another. Typically the locations compared are intracellular vs. extracellular.
C. Osmotic equilibrium occurs when total solute concentration is the same, though chemical disequilibrium may exist.
