Calculate the enthalpy of adsorption of hydrogen gas on platinum at 298 K, given that the maximum coverage of hydrogen on the platinum surface is 0.5 monolayers and the equilibrium constant for the process at 298 K is 2.5 x 10^3. Assume that the adsorption process is exothermic and that the standard enthalpy of formation of water is -286 kJ/mol.

A chemistry student needs to determine the direction in which equilibrium will shift when the concentration of reactants in a reversible reaction is changed using Le Chatelier's principle. Given the reaction equation: 2SO2(g) + O2(g) ⇄ 2SO3(g), if the concentration of SO2 is increased, will the reaction shift to the left or right?
