Extracted text: P19B.2 The data below are for the chemisorption of hydrogen on copper powder at 25°C. Confirm that they fit the Langmuir isotherm at low coverages (the volumes have been corrected so that they are all at the same pressure). Then find the value of a for the adsorption equilibrium and the adsorption volume corresponding to complete coverage. p/Pa 25 129 253 540 1000 1593 V/cm 0.042 0.163 0.221 0.321 0.411 0.471
