How does concentration affect KEQ?
How does concentration affect KEQ?
Changing concentrations Equilibrium constants are not changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a change of temperature. The position of equilibrium is changed if you change the concentration of something present in the mixture.
Is K dependent on concentration?
If you mean the rate constant #k# , then no, it does NOT depend on concentrations at ANY time in the reaction. When we say it is constant, we mean it is constant with respect to concentration, i.e. it is NOT a function of concentration.
What is KEQ equal to?
(1) The equilibrium constant for a reversible chemical reaction. (2) The ratio depicting the concentrations when chemical equilibrium is reached, and expresses the extent to which equilibrium has favoured in either direction. The equilibrium constant is represented by Keq in an equation.
How is KEQ affected by temperature?
Keq is temperature dependent. The reverse is true for exothermic reactions. Adding heat to an exothermic system at equilibrium will cause the system to absorb some of the heat and shift to the reactant side. When concentrations are measured at the new equilibrium, we find a different (smaller) Keq.
Does equilibrium constant depend on stoichiometry?
The value of Kc for a particular chemical reaction at a given temperature depends on how you balance the chemical equation, that is, it depends on the stoichiometric coefficient (mole ratios) for each reactant and product species.
What does it mean if the KEQ is 1?
If Keq is greater than 1, it means the concentrations of the products are greater than those of the reactants. If Keq is less than 1, it means the concentrations of the reactants are greater than the products.
Why is KEQ only affected by temperature?
Does KEQ include aqueous?
Kc is in terms of concentration, so will include aqueous species, mixture of liquids and gases. For Kp we only include the partial pressure of gases, so only partial pressure of B, PB , will be included.
What affects Keq?
Numerical values of Keq are always given at a specific T & P. Rate constant depends only on temperature (also activation energy) and the presence of a catalyst. Whereas the rate of reaction depends on temperature, pressure, time, composition/concentration of reactants as well as the presence of a catalyst.
