3. Consider the ammonia production reaction, N2(g)+3H2(g) + 2NH3 (g). The equi- librium constant for this reaction at 298K is 6.10 x 105. When the system starts with 2 mol of NH3 (no H, or N2), it reaches the equilibrium at the total pressure of 2.0 bar. (a) What is the mole fraction of each species at equilibrium? (b) If we increase the total pressure to 3.0 bar, will it be stimulating the decompo- sition of ammonia? Explain.
