State
A reaction quotient Q has the same form as K but is calculated from concentrations at any moment, not necessarily at equilibrium.
Show
Measuring concentrations partway through a reaction and substituting them into the K expression gives that moment's Q.
Watch for
Q and K share a formula but answer different questions — Q describes now, K describes the equilibrium destination.
