Here's a precise problem for a chemistry student to solve, based on Thermochemistry and the Enthalpy of Desorption Calculations:Given the following data for the adsorption of hydrogen gas on a metal surface:- Initial pressure of hydrogen gas = 1 atm- Final pressure of hydrogen gas after adsorption = 0.2 atm- Temperature = 298 K- Surface area of the metal = 5 cm^2- Enthalpy of Desorption of hydrogen gas on the metal surface = -40 kJ/molCalculate the enthalpy change (in kJ) for the adsorption of hydrogen gas on the metal surface.
