    Effect of the Solution Vapour Pressure on the Temperature Dependence of the Dissociation Constant of Acetic Acid in Water
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (10), 1972) Lown, D. A.; Thirsk, H. R.
    The dissociation constant of acetic acid in water is between 4 and 26% greater at the solution vapour pressure than at one atmosphere in the range 250 to 374°C. K = /(T)s.v.P. corresponds to neither the isobaric nor isochoric conditions, and the error introduced by neglecting the effect of the vapour pressure on the equilibrium at high temperatures is discussed.

    Plateau potentials of the α+β palladium hydride electrode at temperatures between 25 and 195°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (4), 1972) Dobson, J. V.; Dagless, M. N.; Thirsk, H. R.
    The e.m.f. values of cells with respect to time, involving the platinum-hydrogen and (α+β) palladium hydride electrode in hydrogen-saturated aqueous electrolytes are reported between 25 and 195°C and 1–27 atm hydrogen pressure. Relative resistance measurements of the (α+β) palladium hydride electrode as a function of time are also reported under these conditions.

    Some Experimental Factors which Govern the Potential of the Palladium Hydride Electrode at 25 to 195°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (4), 1972) Dobson, J. V.; Dagless, M. N.; Thirsk, H. R.
    A purpose of this paper is to present some of the experimental electrochemical properties of the palladium hydride electrode that have been found between 25 and 200°C. The electrode potentials of palladium hydride were studied in aqueous solutions of sodium hydroxide and hydrochloric acid, in the presence and absence of carbon dioxide and nitrogen. All potentials are measured with respect to a platinum-hydrogen electrode. Use of relative resistance is made to establish the hydrogen-palladium composition and potential dependency as a function of time, temperature and pressure. Some simple polarization studies are also reported on fully equilibrated palladium hydride electrodes.
