equilibrium constant

[‚ē·kwə′lib·rē·əm ‚kän·stənt]
(chemistry)
A constant at a given temperature such that when a reversible chemical reaction cC + bB = gG + hH has reached equilibrium, the value of this constant K 0 is equal to where aG , aH , aC , and aB represent chemical activities of the species G, H, C, and B at equilibrium.
