Question

I just need 70 and 72

Assuming a reaction mixture initially contains only reactants, what is the concentration of CO in an equilibrium mixture with (H2O) = 0.500 M at 1000 °C? 70. Sodium sulfate 10-hydrate, Na2SO 10H20, dehydrates according to the equation Na, SO, 10H,O(s) - Na, SO4(s) + 10H2O(g) Kp - 4.08 * 10-25 at 25°C What is the pressure of water vapor at equilibrium with a mixture of Na SO: 10H,O and NaSO? 71. Calcium chloride 6-hydrate, CaCl2-6H20, dehydrates according to the equation CaCl, 6H2O(8) CaCl (8) + 6H2O(g) Kp - 5.09 10-44 at 25°C What is the pressure of water vapor at equilibrium with a mixture of CaCly-6H 0 and CaCl, at 25°C? 72. A student solved the following problem and found the equilibrium concentrations to be [SO] 0.590 M,[0] = 0.0450 M, and [SO] -0.260 M. How could this student check the work without reworking the problem? The problem was: For the following reaction at 600 °C: 2502(g) + O2(g) = 2503(9) Kc = 4.32

Answer 1

R 70. Na2SO y(s) + 10H20G) Na2S04.10 H2O(g) = Kpo (pyo 4.08x1525 - plo p=104.08 x16 25 P = 0.00 36 4 atm P= 3.64x10 3 atm : 72. For use checking the answer Kc = [50₂]2 0.0676 0.0156645 [02] [502]? Kc = (00260)2 (0.045) * (0.59) KC = 4.32 Hence by using this check the answer you can cross W ARRIOR ARRANRIMPAPSCREWDROPOW R
