Nitrogen gas adsorbed on charcoal to the extent of 0.921 cm3 g1 at 490 kPa and 190 K

Problem 25.13(a)

Nitrogen gas adsorbed on charcoal to the extent of 0.921 cm3 g1 at 490 kPa and 190 K, but at 250 K the same amount of adsorption was achieved only when the pressure was increased to 3.2 MPa. What is the enthalpy of adsorption of nitrogen on charcoal?

                                                               Step by Step Solution

Step 1 of 2

The clausius - Clpyeron equation is as follows.

                                               ...........(1)

From the given,

Initial pressure = 4.8

Final pressure = 3.2

Initial temperature = 190 K

Final temperature = 250 K

Gas constant R =
