摘要

where T(K)is the temperature,x(m)is the Cartesian coordinate and C is the concentration.In a Physics equation all term must have the same units.Therefore from Eq.(1)it is found that the units of constant b must be m_1K and from Eq.(2)it is found that the units of constant b must be concentration m-1.This is impossible because the units of mass concentration is different from Kelvin.Thus either Eq.(1)is wrong or Eq.(2)is wrong.
