# Unit of kc for pcl5

The unit of an equilibrium constant KC for the subsequent chemical reaction is:

## PCl5​⇌PCl3​+Cl2​

We are aware that the constant of equilibrium Kc = concentration of products/concentration of reactants

The equilibrium expression for PCl5 PCl3 Cl3l is:

Kc ​= [PCl5​]

[PCl3​]×[Cl2​]

​Kc​=mole/dm3 X mole/dm3

mole/dm3​

Kc​=mole/dm3

The units of Kc for a reaction between PCl3 and Cl2 to get PCl5 is mole/dm3

What is the unit of KC in the reaction 2SO2 O2 ⇔ 2SO3?

## kc in chemistry stands for?

The equilibrium constant, Kc, is equal to the ratio of the equilibrium concentrations of products to the equilibrium concentrations of reactants multiplied by the stoichiometric coefficients of each reactant and product.

## Formula for Kc

Kc equals [C]c[D]d/[A]a[B]b, where [C] and [D] are the equilibrium molar concentrations of the products and [A] and [B] are the equilibrium molar concentrations of the reactants.
