Question
For the reaction 2 A (g) + B (g) = C(g) + D(s) AH = - 33.0 kJ 1. Initially in a 5.0 L flask at 75°C, there are 0.20 mol A, 0.30 mol C, and 1.00 mol D. When equilibrium is established, Pc = 1.0 atm. What are the partial pressures of all the gases at equilibrium? 2. How many moles of D are present at equilibrium? 3. At what temperature will the equilibrium constant, K, be 1? I need the work for these. The answers to these are: 1: PA = 2.5 atm ; P B = 0.7 atm ; PC = 1.0 atm 2: mols D = 0.88 mol 3: Temperature = 307 K = 34 degrees C
