46. Solving a chemistry problem

6. Adsorption isotherms of gases A and B on some solid are described by the Langmuir equation. At a temperature of 77 K, the degree of surface filling 0 = 0.01 with pure gas A is achieved at pA = 13300 Pa, and with pure gas B at p = 1330 Pa. Calculate the difference between the heats of adsorption of gases A and B.
