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.

Design a heat exchanger for a factory that produces 10,000 liters of sulfuric acid per day starting at 70°C and needs to be cooled to 40°C for packaging. The available cooling water supply from the local municipal is at 20°C and is available at a flow rate of 1000 liters per minute. Design the heat exchanger to achieve the required temperature drop and calculate the heat transfer coefficient and the overall heat transfer coefficient.
