At equilibrium: The rate of the forward reaction is equal to the rate of the reverse reaction. No further changes occur in the concentrations of reactants and products, even though the two reactions continue at equal but opposite rates.
What is the concentration of reactants and products at equilibrium?
All reactions tend towards a state of chemical equilibrium, the point at which both the forward process and the reverse process are taking place at the same rate. Since the forward and reverse rates are equal, the concentrations of the reactants and products are constant at equilibrium.
Are products and reactants equal at equilibrium?
No, concentration of reactants and products are not necessarily equal in a dynamic equilibrium. Equilibrium occurs for a reversible reaction. Reversible means that as reactants bump into each other and become product, products eventually accumulate and bump into themselves, reacting to reform reactants.
How is reaction rate and equilibrium related?
In a chemical reaction, chemical equilibrium is the state in which the forward reaction rate and the reverse reaction rate are equal. The result of this equilibrium is that the concentrations of the reactants and the products do not change.
What is the difference between rate and equilibrium?
In the forward reaction, molecules go from reactant molecules to product molecules. There is a rate associated with this process. In the reverse reaction, the product molecules go to the reactants at another rate. At equilibrium, the rate of the forward and the reverse reactions are equal.
What can change the value of KC?
3 : The only thing which can change the value of Kc for a given reaction is a change in temperature. The position of equilibrium, however, can change without a change in the value of Kc. When the concentration of a reactant is increased, the reaction proceeds forward to decrease the concentration of reactants.
What if equilibrium constant is greater than 1?
The equilibrium constant expression is a mathematical relationship that shows how the concentrations of the products vary with the concentration of the reactants. If the value of K is greater than 1, the products in the reaction are favored. If K is equal to 1, neither reactants nor products are favored.Tir 10, 1398 AP
