2023年1月30日 · This page explains equilibrium constants expressed in terms of partial pressures of gases, K p. It covers an explanation of the terms mole fraction and partial pressure, and looks at Kp K p for both homogeneous and heterogeneous reactions involving gases.

In this case, to use K p, everything must be a gas. If you allow this reaction to reach equilibrium and then measure (or work out) the equilibrium partial pressures of everything, you can combine these into the equilibrium constant, K p.

2024年10月25日 · Revision notes on Kp Expressions for the AQA A Level Chemistry syllabus, written by the Chemistry experts at Save My Exams.

For a general reaction of gases, the equilibrium constant Kp can be represented as: aA + bB ⇆ cC + dD. Let’s see an example of calculating Kp. Example: The following equilibrium pressures were observed at a certain temperature for the Haber process: 3H 2 (g) + N 2 (g) ⇆ 2NH 3 (g) P (NH 3) = 5.2 x 10 9 atm. P (N 2) = 6.1 x 10 2 atm.

2024年5月29日 · The Kp calculator is a tool that will convert the equilibrium constant, Kc, to Kp - the equilibrium constant in terms of partial pressure. In the following article we will explain what is Kp, as well as providing you with the Kp equation.

2023年10月30日 · In chemistry, Kp stands for the equilibrium constant that is associated with the partial pressures of gases in a chemical reaction at equilibrium. It quantifies the ratio of the partial pressures of products to reactants in a gaseous equilibrium.

2016年5月1日 · What are the partial pressures of the 3 gases? Only include gases in the Kp expression. Ignore solids, liquids, and aqueous substances. Unit = kPa-2 However, if the equation is written the other way round, the value of Kp will be …

2017年10月23日 · Equilibrium Constant Kp Definition. When a reaction is at equilibrium, the forward and reverse reaction rate are same. The concentration of the reactants and products stay constant at equilibrium, even though the forward and backward reactions are still occurring.
