Consider the synthesis of ammonia: 3H2(g) + N,(g) = 2NH3(g), which has AH° = -92.4 kJ/mol and AS° = -199 J/mol at 298 K. For this problem, you may assume all gases behave ideally. a. Calculate Kp for this reaction. b. If a mixture of 1.00 mol H2 and 1.00 mol of N2 is combined in a 10.0 L container and allowed to reach equilibrium, use Kp to calculate the final pressures of H2 and N2. c. Calculate Kc for this reaction. d. If a mixture of 1.00 mol H2 and 1.00 mol of N2 is combined in a 10.0 L container and allowed to reach equilibrium, use Kc to calculate the final concentration of H2 and N2. e. Convert your answers from part (b) and part (d) into the same units -- how do they compare?
