Rearranging the Eyring equation leads to the following: where is the rate constant, is the Planck constant, is the universal gas constant, is the Boltzmann constant, is temperature, is enthalpy, and is entropy. The entropy term should ultimately be in units of . The right term of the equation will clearly yield the correct units.
