  • Kinetics of Activated Chemisorption Pari 3.—Amount and Distribution of Adsorbate at Varying Temperatures and Pressures 
    Aharoni, Chaim; Ungarish, Moshe (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (12), 1977)
    The heterogeneous-surface model applied in Part 2 to the kinetics, is now applied to the effects of temperature and pressure on the amount adsorbed. It predicts isobars with a maximum that is displaced towards higher ...
  • Kinetics of activated chemisorption. Part 2.—Theoretical models 
    Aharoni, Chaim; Ungarish, Moshe (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (03), 1977)
    In activated chemisorption the plot of the reciprocal of the rate Z=(dq/dt)–1 against the time t is convex towards the Z axis at low t and concave at high t. This condition is satisfied if both the energy of activation, ...
  • Kinetics of activated chemisorption. Part 4.—Differential heat of adsorption 
    Aharoni, Chaim; Ungarish, Moshe (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1978, 74 (06), 1978)
    A model previously applied to the kinetics of chemisorption and to adsorption at true and apparent equilibrium, is applied to the differential heats of adsorption. The measurable function, heat-coverage, differs from the ...
  • Kinetics of Chemisorption Deducing Kinetic Laws from Experimental Data 
    Ungarish, Moshe; Aharoni, Chaim (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1981, 77 (05), 1981)
    The kinetics of chemisorption have been inadequately represented in the literature by second-order equations and by Elovich equations. The conditions at which non-valid equations become apparently applicable are discussed. ...
