Kc is the equilibrium constant and is the ratio of the activity of the reactants (numerator) to the activity of the product (denominator). The activity of each component is raised to the power of its corresponding chemical stoichiometric coefficient. Since the activity of each chemical is unitless, the equilibrium constant will also have no units.
Example:
For equilibrium of chemicals in the gas phase, each activity will be measured by its partial pressure (units of pressure) multiplied by its fugacity (units of 1/pressure), so the activity of each gas participating in the equilibrium will be unitless, and the corresponding ratio (Kc) will be unitless.

What are the units of equilibrium constant Kc?
The units of equilibrium constant Kc are mol/Ln, where n is the sum of the stoichiometric coefficients of the products minus the sum of the stoichiometric coefficients of the reactants in the balanced chemical equation.
What are Kp aND KC?
Kp and Kc are equilibrium constants in chemistry. Kp is the equilibrium constant expressed in terms of partial pressures of gases, while Kc is the equilibrium constant expressed in terms of molar concentrations of reactants and products in a homogeneous system.
How can one determine the equilibrium constant Kp from the equilibrium constant Kc?
To determine the equilibrium constant Kp from the equilibrium constant Kc, you can use the ideal gas law equation. The relationship between Kp and Kc is given by the equation Kp Kc(RT)(n), where R is the gas constant, T is the temperature in Kelvin, and n is the difference in the number of moles of gaseous products and reactants. By using this equation, you can calculate the equilibrium constant Kp from the given equilibrium constant Kc.
How can one determine the equilibrium concentration using the equilibrium constant, Kc?
To determine the equilibrium concentration using the equilibrium constant, Kc, you can set up an expression that relates the concentrations of the reactants and products at equilibrium. The equilibrium constant, Kc, is calculated by dividing the concentration of the products by the concentration of the reactants, each raised to the power of their respective coefficients in the balanced chemical equation. By rearranging the equation, you can solve for the unknown concentration to find the equilibrium concentration.

What is the difference between Kc and Kw for water?
Kc is the equilibrium constant for a chemical reaction involving water, whereas Kw is the equilibrium constant for the autoionization of water to form hydronium and hydroxide ions. Kw has a fixed value at a given temperature (1.0 x 10^-14 at 25°C), while Kc can vary depending on the specific chemical reaction.
For which reactions can you select the reactions where Kp is equal to Kc?
For reactions involving gases, you can select reactions where the equilibrium constant Kp is equal to the equilibrium constant Kc.
What is the effect of pressure and concentration on Kc and Kp values?
Kc is the equilibrium constant of a chemical reaction related to concentrations. Kp is the equilibrium constant of a chemical reaction related to pressures. Generally, in normal conditions the effect of temperature is not so important.
What is the difference between the equilibrium constants Kc and Kp in a chemical reaction?
The equilibrium constant Kc is used for reactions in a liquid or aqueous solution, while Kp is used for reactions in a gas phase. Kc is based on concentrations of reactants and products, while Kp is based on partial pressures of gases.
What does K subscript c mean?
The constant Kc appears in the equation ~ Kp= Kc(RT)Delta n and Kc = Kp(RT)Delta -nit is derived from the ideal gas law equation PV=nRT,where P is isolated so that P=(n/V)RT, and n/V is converted to a C for concentration, (#mols/Liters being a concentration). Therefore, the constant Kc is merely the constant used at a specific concentration (which is not the concentration at equilibrium), but only when pressure changes are also involved.
What is the Kc value for FeSCN?
The equilibrium constant Kc for the formation of FeSCN2+ is around 685 M^-1.
