The symbol for the
Equilibrium Constant is
Keq.
To find the
equilibrium constant, you use the
equilibrium constant expression. The rule for the
equilibrium constant expression is as follows:
For the following reaction at equilibrium:
aA+bB <=> cC + dD
The Equilibrium Constant Expression is:
[C]c × [D]d
Keq = ____________
[A]a × [B]b
In other words, it is the concentrations of the
products over the
concentrations of the
reactants, with each
element being raised to the
power of its
coefficient.
