What effects does catalysts have to rate of reaction?
In the presence of catalysts the rate of reaction is higher.
What effects do catalysts have on chemical rections?
Catalysts generally speed up chemical reactions.
What effects kc equillibrium?
The equilibrium constant (Kc) is affected by changes in temperature, concentration, and volume of the reacting species. An increase in temperature typically shifts the equilibrium position for endothermic reactions, increasing Kc, while it decreases for exothermic reactions. Changes in concentration or volume can shift the equilibrium position but do not alter the value of Kc at a given temperature. Additionally, the presence of catalysts can speed up the rate of reaching equilibrium but does not affect the equilibrium constant itself.
Do catalyst increase equilibrium constant?
No they do not. A catalyst is a thing (atom, molecule, element, etc.) that speeds up a chem. rxn by lowering the activation energy without being altered itself. So it only cause the reaction to occur faster, but will not have any affect on the equilibrium. Also, since the catalyst is not altered, it should 'come out' exactly as it 'went in.'
What do catalysts do to the digestive system?
nothing
What does Le Châtelier's principle say about upsetting a system at equilibrium?
When a change is imposed on a system at equilibrium, the "position" of the equilibrium shifts in a direction that reduces the effects of that change. For example, if a reactant or product is added, the system shifts AWAY FROM that added component to use the excess up. If heat is added, the system shifts AWAY FROM that added energy energy to use the excess up. If the pressure on a system is increased, the system shifts toward the side with fewer gas molecules.
What is the Medical term meaning equilibrium of a system?
Homeostasis means equilibrium of a system.
What is the types of equilibrium?
There are three types of equilibrium: stable equilibrium, where a system returns to its original state after a disturbance; unstable equilibrium, where a system moves further away from its original state after a disturbance; and neutral equilibrium, where a system remains in its new state after a disturbance.
What effect does a promoter catalyst have on the position of the equilibrium?
By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.
What does Le chateliers principles say about upsetting a system at equilibrium?
Le Chatelier's principle says that if a system in chemical equilibrium is disturbed, the system will move in such a way as to nullify that change.
What are the key differences between unstable and stable equilibrium in a system?
In a system, unstable equilibrium occurs when a small disturbance causes the system to move further away from its original position, while stable equilibrium occurs when a small disturbance causes the system to return to its original position. The key difference lies in how the system responds to disturbances, with unstable equilibrium leading to further movement away from equilibrium and stable equilibrium leading to a return to equilibrium.
What happens when reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.
