What would happen to the equilibrium potential of Na if you change the concentration of K inside the cell?
The equilibrium potential of sodium (Na) is primarily determined by the concentration of Na ions inside and outside the cell, as described by the Nernst equation. Changing the concentration of potassium (K) inside the cell does not directly affect the equilibrium potential of Na. However, alterations in K concentration can influence the overall membrane potential and the activity of sodium channels, which may indirectly affect the dynamics of Na influx during action potentials. Thus, while the Na equilibrium potential remains unchanged, the cell's excitability and response to stimuli could be affected.

Based on diffusion what will happen to the substances inside and outside of the cell?
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
What will happen to a weak acid dissociation equilibrium if more reactants were added?
Concentration of products would increase in order to attain equilibrium in the system again.For example:H2CO3 --> H+ + HCO3-K= ([H+][žHCO3-])/([H2CO3])K is constant for this process, so if you increase the concentration of reactants (H2CO3), in order for K to stay the same, concentration of products (H+, HCO3-) would also have to increase.It's part of Le Chatelier's principle: "If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established."So, in your case, adding more reactant would cause equilibrium to shift to the right (toward products), and therefore, their concentration would increase so that new equilibrium could be established.
What will happen to the concentration of reactants after an equilibrium reaction shifts to the left?
Increasing the concentration of reactants will shift the equilibrium towards the products. The equilibrium will always shift to reduce the change you caused. If you add more products, it shifts toward reactants. This is known as the Le Chatelier Principle.See the Web Links to the left of this answer for more about this.
Does dynamic equilibrium always happen when a change occurs?
No, this is not necessarily.
According to Le Châtelier's principle what would happen if the equilibrium of a weak acid or weak base were upset?
According to Le Châtelier's principle, if the equilibrium of a weak acid or weak base is disturbed by changes in concentration, temperature, or pressure, the system will adjust to counteract that change and restore a new equilibrium. For example, if the concentration of a weak acid is increased, the equilibrium will shift to the left, favoring the formation of reactants and reducing the concentration of hydrogen ions. Conversely, if a weak base's concentration is increased, the equilibrium will shift to the right, producing more hydroxide ions. This principle helps to understand how systems respond to external changes in order to maintain stability.
What happen to the movement of molecules at equillimbrium?
The movement of molecules at equilibrium is determined by Le Chatalier's principle. This basically says that if you change a reaction to favour one side, the equilibrium will try and counteract this change. The three things that can affect an equilibrium is temperature, pressure and concentration.
Based on diffusion what will happen to the substances inside and outside of the cell?
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
According to le chatelier principle what would happen to a system at equilibrium if more of one compound in a reaction were added?
All concentrations would change (apex)
What causes the equilibrium to shift to the left?
The equilibrium shifts to the left when there is an increase in the concentration of reactants or a decrease in the concentration of products. This can also happen when the temperature is decreased in an exothermic reaction.
What would happen to a a system at equilibrium if the temperature were changed?
the equilibrium constant would change
What would happen to a system a equilibrium if the temperature were changed?
the equilibrium constant would change

When and where does diffusion happen?
Diffusion can happen anytime and anywhere there is a concentration gradient. It is a passive process where particles move from an area of high concentration to an area of low concentration to achieve equilibrium. Examples include the exchange of gases in the lungs during breathing and the movement of nutrients into cells.
What would happen if the equilibrium of a weak dissociation reaction were upset?
