Definition of equilibrium constant Kp for gas phase reactions, and how to calculate Kp from Kc.

In this video, we'll calculate equilibrium constants using measurements of concentration and partial pressures at equilibrium. First, we'll find Kc for an equilibrium system using equilibrium …

If we were to write a Kp expression here, we would include the partial pressure of our gas, which is carbon dioxide. So this would be the partial pressure of carbon dioxide to the first power. And once …

Definição da constante de equilíbrio Kp para reações na fase gasosa e como calcular Kp a partir de Kc.

So, we would write Kp is equal to, and for our products, we have PCl3, so this would be the partial pressure of PCl3 times the partial pressure of our other product, which is Cl2, so let's put in there the …

Definición de la constante de equilibrio Kp para reacciones en fase gaseosa y cómo calcular Kp a partir de Kc.

Kc y Kp suelen tener valores diferentes entre sí. De modo que si volvemos a la reacción anterior donde todo estaba en estado gaseoso, podríamos escribir una expresión Kp.

Definition of equilibrium constant Kp for gas phase reactions, and how to calculate Kp from Kc.

We typically refer to that value as K p to tell it apart from the equilibrium constant using concentrations in molarity, K c . In this article, however, we will be focusing on K c .

Primeiramente, vamos calcular Kc de um sistema em equilíbrio usando concentrações de equilíbrio. Depois, vamos calcular Kp de um sistema diferente usando pressões parciais de equilíbrio. Versão …
