Calculate the enthalpy of adsorption for a reaction where 2 moles of nitrogen gas (N2) are adsorbed on the surface of a solid at -100°C. Given that the partial pressure of N2 in the gas phase is 0.2 atm and the equilibrium constant for adsorption of N2 at this temperature is 2.5 x 10^3. Assume the adsorption is a reversible process and that the ideal gas law can be used to calculate partial pressures.
