Equilibrium Constant ( KC )

The equilibrium constant of a chemical reaction is the value of the reaction quotient when the reaction has reached equilibrium. At any given temperature, the equilibrium constant has a value which is independent of the initial and actual concentrations of the reactant and product speciesmore info

Reference : http://scienceaid.co.uk/chemistry/physical/eqconstants.html


To calculate Kc you take the concentrations of the products, and then do each one to the power of the number of moles of it, from a balanced equation. Then do the same for the reactants, and divide products by reactants. more info

** No need to concern about the units of KC

Additionally, the equilibrium constant can be used to determine the composition of a system at equilibrium via equilibrium will.

  1. I'm curious if this formula works all the time? Without any exceptions? Btw, your blog is amazing!

    1. Yes, it works all the time. You can also use this formula in equilibrium disturbance case.
