Question

The equilibrium constant has no units if the number of moles of products are:

Options
  • A

    Less than reactants

  • B

    More than reactants

  • C

    Equal to reactants

  • D

    Half of reactants

Explanation

This is correct. If the number of moles of products and reactants are equal, the units cancel out, resulting in a dimensionless equilibrium constant.

This is incorrect. The units of the equilibrium constant depend on the difference in moles.

This is incorrect. The units of the equilibrium constant depend on the difference in moles.
