Equilibrium constant - Wikipedia, the free encyclopedia
For a general chemical equilibrium the equilibrium constant can be defined by where {A} is the activity of the chemical species A, etc. (activity is a dimensionless quantity). It is conventional to pu...

The concept of equilibrium is an extremely important one to master. It helps to explain the behavior of chemical reactions and buffer systems, and can be used to drive reactions that normally don't ... Kc has a constant value at a given temperature, independent of original concentration, volume of container, or pressure.
