ng point determination can be used for several purposes. What are those purposes? effect on the boiling point is produced by: 1) a soluble non-volatile impurity, such as table salt ) an insoluble foreign substance, such as sand id “X" has a normal boiling point of 75 °C. What will be the approximate boiling p d at 800 mmHg pressure?

A mixture consiting of 1.000 mol H2O(g) and 1.000 mol CO(g) is placed ina  reaction vessel of volume 10.00 L at 800. K. At equilibrium, 0.665 mol CO2(g) is present as a result of the reaction CO (g) + H2O (g)⇋ CO2(g)+H2(g). What are the equilibrium concentrations for all substances?

A mixture of 2.75e-02 mol of O, 4.32e-02 mol of NOCI, 7.25e-02 mol of NO, and 7.59e-03 mol of Cly is placed in a 1.0-L steel pressure vessel at 1654 K. The following equilibrium is established: Ox(9) + 2 NOCI(9) =2 NO;(0) + Ch(9) At equilibrium 6.01e-03 mol of Clz is found in the reaction mixture. Calculate the equilibrium pressures of all gases in the reaction vessel and the value of Kp for the reaction. Pick the correct statement from the multiple choices, Use the value R= 0.0821 L-atm/mal-K for the gas constant. Oa) The equilibrium pressure of NOCI is PNoc 6.29 atm. O b) The equilbrium pressure of O2 is Po, 3.52 atm. O9 The equilbrium constant is Kp 9.2e-02. O4) The equibrum constant is Kp 2.2e+00. Oe) The equilibrium pressure of NO is PNo, 10.3 atm.
