Final answer:
Chemical reaction equilibrium occurs when the forward and reverse reactions of a chemical reaction are happening at the same rate. Chemical equilibrium is a specific type of chemical reaction equilibrium where the concentrations of reactants and products reach a steady state. Osmotic equilibrium refers to the equal concentration of solute on both sides of a semi-permeable membrane.
Step-by-step explanation:
Chemical reaction equilibrium refers to the state where the forward and reverse reactions of a chemical reaction are occurring at the same rate. At this point, the concentrations of reactants and products remain constant. A chemical equilibrium, on the other hand, is a specific type of chemical reaction equilibrium where the concentrations of reactants and products reach a steady state, but not necessarily equal concentrations. Osmotic equilibrium refers to the state where there is no movement of solvent across a semi-permeable membrane due to an equal concentration of solute on both sides.
