ViviWhen equilibrium is reached in a solution, the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time. At equilibrium, the system is dynamically stable, with no net changes occurring in the concentrations of reactants and products.

Does diffusion ever stop?
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.
When does an equilibrium occur?
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.
A dynamic equilibrium is reached when hydrogen cyanide acid is dissolved in water Which species is present in the highest concentration in this solution?
In a dynamic equilibrium with hydrogen cyanide dissolved in water, the majority of the solution will contain undissociated hydrogen cyanide molecules. This means that hydrogen cyanide (HCN) in its molecular form will be present in the highest concentration. There will also be some hydronium ions (H3O+) and cyanide ions (CN-) in solution due to partial dissociation.
How does the time it takes for equilibrium to be reached affected by temperature increases?
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.
How do you know that thermal equilibrium has been reached between two objects?
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.
