Huttig equation [′həd·ik i‚kwā·zhən] (thermodynamics) An equation which states that the ratio of the volume of gas adsorbed on the surface of a nonporous solid at a given pressure and temperature to the volume of gas required to cover the surface completely with a unimolecular layer equals (1 +r)cr/(1 +cr), whereris the ratio of the equilibrium gas pressure to the saturated vapor pressure of the adsorbate at the temperature of adsorption, andcis the product of a constant and the exponential of (q-ql)/RT, whereqis the heat of adsorption into a first layer molecule,qlis the heat of liquefaction of the adsorbate,Tis the temperature, andRis the gas constant.
