3. Nitrogen and hydrogen react to form ammonia. \mathrm{N}_{2}+3 \mathrm{H}_{2} \rightarrow 2 \mathrm{NH}_{3} This reaction provides the basis for most of synthetic fertilizers and is catalyzed by Fe or Ru

catalysts A. Calculate the Gibbs Free Energy of the reaction at 298 K (3 pts). B. Calculate the enthalpy of the reaction at 298 K (3 pts) C. Nitrogen (100 mol/h) and hydrogen (300 mol/h) are fed into a gas-phase flow reactor maintained at 20 bar and 773 K. Calculate the Gibbs Free Energy of reaction at that temperature. You may assume the enthalpy of the reaction is constant. (6pts) D. Calculate the equilibrium constant of the reaction at 773 K (3 pts) E. Calculate the extent of reaction at equilibrium (7 pts). You may assume that the gas phase is ideal. F. How would you calculate the extent of reaction if the gas phase were not ideal? (4pts) G. The equilibrium extent of reaction will be highest at (2 pts): i. High temperature, high pressure ii. Low temperature, high pressure iii. High temperature, low pressure iv. Low temperature, low pressure H. Explain (3 pts) Why does the industry not run the reaction at the conditions you chose above? (3pts)I.
