* forward rate = reverse rate
* constant environmental conditions (e.g.: T, P, etc.; otherwise, Le Chatelier's Principle comes into effect)
* closed system
Diffusion will continue as long as there is a concentration gradient present. Once equilibrium is reached and the concentrations are equal throughout, diffusion will stop.
An equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time. Equilibrium can only be reached in a closed system under certain conditions, such as constant temperature and pressure.
C2H3O2-(aq) H+(aq) H3O+(aq) OH-(aq) HCN(aq)Those are the choices that could be given, but the answer is HCN. It can't be H+ or OH- because the water is de-ionized and H3O+ is not possible.
An increase in temperature can generally speed up the time it takes for equilibrium to be reached in a chemical reaction. This is because higher temperatures provide more energy to the reactant molecules, increasing their kinetic energy and collision frequency, which in turn accelerates the rate of the reaction towards equilibrium.
Thermal equilibrium between two objects is reached when they have the same temperature and there is no net flow of heat between them. This can be determined by measuring their temperatures over time and observing that they remain constant and equal.
Equilibrium solubility is how much of a certain solute is in solution when the system has reached equilibrium. For example, when something like silver chloride (AgCl) is placed in water, none of it goes into solution. But given some time, an equilibrium will be reached where a small amount of AgCl is in solution and is in equilibrium with the insoluble AgCl.
dynamic equilibrium
Diffusion will continue as long as there is a concentration gradient present. Once equilibrium is reached and the concentrations are equal throughout, diffusion will stop.
Equilibrium is reached, the solution is isotonic.
Something is in "equilibrium" when it is in a state of perfect balance or rest. All forces acting on it are equal and opposite. It is in a "minimum" energy state.
Of course they. If not, they would not be "in solution".If substances of a solution are evenly distributed then they have reached equilibrium.
When the number of molecules crossing the membrane is the same in both directions, equilibrium is reached. This means that a state of balance has been achieved, where there is no net movement of molecules across the membrane.
A super saturated solution is unstable, and wants to precipitate some solute to regain a stable situation. Dissolve something in water at a high temperature in a perfectly clean glass container, until no more dissolves. Cool slowly and the solution becomes unstable because it holds more in solution than is normal at equilibrium at that lower temperature. It is super saturated. A tiny speck of dust or even agitation can provide conditions where the excess can precipitate out as a solid particles in suspension, until the equilibrium concentration of solution is reached, but with clouds of precipitate in there.

an equilibrium
When equilibrium is reached, the fluid levels may not necessarily be the same as they are now. Equilibrium refers to a state where the forces or concentrations are balanced, leading to no net change in the system. However, the final fluid levels depend on factors such as the initial conditions and the specific processes involved in reaching that equilibrium. Thus, while the system will stabilize, the fluid levels could differ from their initial values.
At equilibrium its not changing (any more).
