***Dropping a drop of red dye into water
The equilibrium constant:
is described as K = [products]/[reactants] without reference to coefficients within the chemical
equation
is described as K = [reactants]/[products] without reference to coefficients within the chemical
equation
***is described as K = [reactants]/[products] with reference to coefficients within the chemical
equation (used as superscripts)
