What is the equilibrium expression for the dissolution of Ag2CO3?
The equilibrium expression for the dissolution of Ag2CO3 is: Ag2CO3(s) ⇌ 2Ag+(aq) + CO3^2-(aq).
What is the correct form for the equilibrium constant expression for this reaction H2g plus F2g 2 HFg?
The correct form for the equilibrium constant expression for this reaction is Kc = [HF]^2 / ([H2] * [F2]), where the square brackets denote molar concentrations of each species at equilibrium.
Which species are left out from the Keq expression?
The substances left out from the equilibrium constant expression (Keq) are usually pure solids, pure liquids, and solvents. These do not affect the equilibrium position because their concentrations remain constant. Only species that are present in aqueous or gaseous form and participate in the reaction are included in the Keq expression.
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
What is the significance of Kc in equilibrium expression?
Kc is the equilibrium constant.
The equilibrium constant for the reaction below is 0.49 At equilibrium O2 equals 0.11 and N2 equals 0.15 What is the equilibrium concentration of NO?
To find the equilibrium concentration of NO, first calculate the equilibrium constant expression using the given concentrations of O2 and N2. Then, rearrange the equilibrium constant expression to solve for the concentration of NO. Finally, substitute the values of O2 and N2 concentrations into the rearranged expression to find the equilibrium concentration of NO.

What does equilibrium and equilibrium mixture mean?
A quantity that characterizes the position of equilibrium for a reversible reaction; its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
Why is it important to write a balanced reaction before determining the equilibrium expression and equilibrium concentrations?
So you can use the coefficants to go from one substance to another

The correct form for the equilibrium constant expression for this reaction is Kc = [HF]^2 / ([H2] * [F2]), where the square brackets denote molar concentrations of each species at equilibrium.
How can you use a balanced chemical equation to write an equilibrium constant expression?
To write an equilibrium constant expression using a balanced chemical equation, you need to identify the reactants and products involved in the equilibrium and write the expression as a ratio of the products raised to their stoichiometric coefficients divided by the reactants raised to their stoichiometric coefficients. The general format is [products]/[reactants]. The coefficients from the balanced equation become the exponents in the expression.
How can one determine the equilibrium concentration in a chemical reaction?
To determine the equilibrium concentration in a chemical reaction, one can use the equilibrium constant, which is a ratio of the concentrations of products to reactants at equilibrium. By knowing the initial concentrations and the stoichiometry of the reaction, one can calculate the equilibrium concentrations using the equilibrium constant expression.
How can one determine the equilibrium concentration of FeSCN2 in a chemical reaction?
To determine the equilibrium concentration of FeSCN2 in a chemical reaction, you can use the equilibrium constant expression and the initial concentrations of the reactants. By setting up an ICE table (Initial, Change, Equilibrium), you can calculate the equilibrium concentration of FeSCN2 based on the stoichiometry of the reaction and the equilibrium constant value.
The equilibrium constant for the reaction below is 0.625. At equilibriumO 2 0.40 and H2O 0.20. What is the equilibrium concentration of H2O2?
Given the equilibrium constant (Kc) is 0.625 and the concentrations of O2 and H2O at equilibrium are 0.40 and 0.20 respectively, you can use the equilibrium expression Kc = [H2O2] / ([O2] * [H2O]) to solve for the equilibrium concentration of H2O2. Plugging in the values, you can calculate the concentration of H2O2 at equilibrium.
What is the expression that represents the equilibrium constant expression for H2SO3?
H2SO3 will ionize to H+ + HSO3-. The Keq = [H+][HSO3-]/[H2SO3]HSO3- will ionize to H+ + SO3^2-. The Keq = [H+][SO^2-]/[HSO3-] ... very small value
Which species are left out from the Keq expression?
The substances left out from the equilibrium constant expression (Keq) are usually pure solids, pure liquids, and solvents. These do not affect the equilibrium position because their concentrations remain constant. Only species that are present in aqueous or gaseous form and participate in the reaction are included in the Keq expression.
