Determine the enthalpy of adsorption for the reaction of hydrogen gas adsorbing onto a platinum surface, given that 2.00 g of hydrogen gas is adsorbed onto a 1.00 g platinum surface at 25°C and the pressure is 1 bar. The volume of the system is 1.00 L and the initial temperature of the platinum surface is also 25°C. Assume that the surface is in thermal equilibrium with the surroundings and that the gas behaves ideally.
