14. Ammonia can be synthesized by this reaction: 3 H2(g) +N2(g) ? 2NH3(g) a) Assume the reaction occurs at STP (1 atm, 273 K). How many liters of ammonia can theoretically be produced if 202 g of hydrogen react completely? Given: R=0.0821 L*atm/mol K b) The reaction enthalpy for the above reaction is -92.4 kJ/mol. Is heat released or consumed in this process, and how much?
Expert Answer
a) Molar mass of H2 = 2g/mol Moles of H2= Mass/ molar mass = 202/2 =101 moles Mo
