Is a condition in which the concentration of a substance is equal throughout a space.
The equilibrium constant (K) is used to describe the conditions of a reaction at equilibrium. It provides information about the relative concentrations of products and reactants at equilibrium.
The equilibrium potential refers to the electrochemical potential at equilibrium of a particular ion, as calculated by the Nernst equation. The resting potential refers to the weighted average based upon membrane permeabilities of all the equilibrium potentials of the various ions in a given cell, as calculated by the Goldman equation.
Equilibrium potential is referring to the equilibrium (or balance) established between the forces of diffusion and electrical forces specific to each ion. For example, the equilibrium potential for Potassium, K+, in a cell with a semi permeable membrane is -80mV or Ek+=80mV. The membrane potential, on the other hand, refers to the voltage across the membrane at anytime and takes into account a range of equilibrium potentials such as Potassium, Sodium etc.
At equilibrium distance, the forces between atoms or molecules are balanced, resulting in stable and minimum potential energy. Any deviation from this distance would cause a change in potential energy as the forces try to bring the atoms back to equilibrium. This results in a minimum potential energy state at the equilibrium distance.
At equilibrium potential, the forces on an ion are balanced, meaning there is no net movement of ions across the membrane. The electrical force due to the membrane potential balances the chemical force due to the concentration gradient, resulting in equilibrium. This can be seen in action for ions like potassium (K+) at its equilibrium potential in a resting neuron.
At equilibrium the concentrations of reactants and productas remain constant.
At equilibrium the concentrations of reactants and productas remain constant.
The equilibrium potential is important in determining the resting membrane potential of a cell because it represents the voltage at which there is no net movement of ions across the cell membrane. At this point, the concentration gradient and electrical gradient for a specific ion are balanced, resulting in a stable resting membrane potential.

If you decrease the extracellular sodium concentration, the equilibrium potential of sodium shifts towards a more negative value. This is because there is less sodium available to drive the sodium ions into the cell, causing the equilibrium potential to become more negative.
The equilibrium potential for sodium (ENa) is around +60 mV. This is the membrane potential at which there is no net movement of sodium ions across the membrane, as the concentration gradient is balanced by the electrical gradient.
The chloride equilibrium potential plays a crucial role in determining the overall membrane potential of a cell. It is the point at which the movement of chloride ions across the cell membrane is balanced, influencing the overall electrical charge inside and outside the cell. This equilibrium potential helps regulate the cell's resting membrane potential and can impact various cellular functions and signaling processes.
