(a) (b) (c) The adsorption of a gas is described by the Langmuir isotherm with K = 4.9 kPa¹¹ at 25°C. Calculate the pressure at which the fractional surface coverage is 0.25 and 0.75. The data in Table 8 is for the hydrogen chemisorption on copper powder at 25°C. Find the value of K for the adsorption equilibrium and the adsorption volume corresponding to complete coverage.
