*I want to know the enthalpy of the products at 1700C, and accurate value. Problem 7 Current fuel cell technology usually uses hydrogen as the fuel which is usually formed from fossil fuels in an apparatus known as a fuel reformer. There are many possible sources of hydrogen including water, natural gas, and coal. In one possible coal gasification process, coal (assumed to be 100% carbon) is reacted with water to produce carbon dioxide and hydrogen. One possible design for this process is shown in the sketch below. For each mole of carbon entering the reactor, two moles of water enter. Both reactants are at a temperature of T₁ = 25 C and a pressure of P₁ = 1 atm. Because the oxidation is incomplete at the desired product temperature of T₂-1700 C, the products of the reaction are CO2, CO, H2, O2, and H₂O. (a) What heat transfer is necessary to produce this product stream from the reactant stream? Be sure sign is correct. (b) At the equilibrium product temperature of 1700 C, how many moles of H₂ are produced for each mole of carbon reacted? (c) Would the yield of hydrogen be increased or decreased by increasing the pressure in the product stream? C H₂O Steady-state reaction chamber Products
