e) It has a unit of measure.
Keq does not have a unit of measure. It represents the ratio of the concentrations or partial pressures of products to reactants at equilibrium and is therefore a dimensionless quantity.
Which statement about Keq is not true?
a) It is affected by changes to the equilibrium system.
b) It has a numerical value.
c) It can be used to determine the unknown concentration of a reactant.
d) It can be used to determine the unknown concentration of a product.
e) It has a unit of measure.

are you sure?
Yes, I am sure. Keq is a dimensionless quantity because it is a ratio of concentrations or partial pressures. It represents the equilibrium constant and is defined as the ratio of the concentrations of products to the concentrations of reactants, with each term raised to the power of its stoichiometric coefficient in the balanced chemical equation. Keq does not have any units of measure.
