1. The problem statement, all variables and given/known data Given: (1/2) mol N2 + (3/2) mol H2 -> NH3 change in H = -46.11 kJ/mol If the number of moles of N2 are changed to 10 and the number of moles of H2 to 35, how much heat is generated if only 10% of the Nitrogen reacts? 3. The attempt at a solution After setting up a ratio, I find that 10 moles of N2 can produce 20 moles of NH3. Thus, 10% of the N2 means 10% of the NH3, so 2 moles of NH3 are produced. I multiple 2 by the original energy to achieve -92.22kJ. Did I do this correctly?
