Chemistry Kc Equation ~ Substitute the equilibrium into the equilibrium law. The equilibrium constant is the value of the reaction quotient that is calculated from the expression for chemical equilibrium it depends on the ionic strength and temperature and is independent of the concentrations of reactants and products in a solution. Science ap college chemistry chemical equilibrium equilibrium constant calculating equilibrium constant kp using partial pressures definition of equilibrium constant kp for gas phase reactions and how to calculate kp from kc. To do the calculation you simply plug in the equilibrium concentrations into your expression for kc. Use stoichiometry to fill in the rest of the chart with x s. Pb 0 3 mol l i 0 2 mol l pbi 2 0 5 mol l. Compare this with the chemical equation for the equilibrium. B mole of reactant b. Next calculate find kc. K equ k f k b pc c pd d pa a pb b k p. Indeed lately has been sought by consumers around us, perhaps one of you. People now are accustomed to using the net in gadgets to see video and image information for inspiration, and according to the name of the article I will talk about about Chemistry Kc Equation. Set up the chart. Given kc and initial 1. Compare this with the chemical equation for the equilibrium. K equ k f k b pc c pd d pa a pb b k p. Science ap college chemistry chemical equilibrium equilibrium constant calculating equilibrium constant kp using partial pressures definition of equilibrium constant kp for gas phase reactions and how to calculate kp from kc. B mole of reactant b. Equilibrium constant definition. For reactions involving gases. To learn more about equilibrium constant k c go to the equilibrium constant. This occurs when the forward and reverse reactions occur at equal rates.
Isolate and solve for x. The indices the powers that you have to raise the concentrations to for example squared or cubed or whatever. To learn more about equilibrium constant k c go to the equilibrium constant.
Use stoichiometry to fill in the rest of the chart with x s.
To do the calculation you simply plug in the equilibrium concentrations into your expression for kc. The convention is that the substances on the right side of the equation are written in the numerator of the k c expression and those on the left side in the denominator. In the following article we will explain what is k p as well as providing you with the k p equation. Compare this with the chemical equation for the equilibrium.
