Unformatted text preview: Name: ___________________________________ CH101 Partial Pressure – Study Guide section 5.6 in the textbook Partial Pressures Dalton’s law of partial pressures states: __________________________________________________________________________ __________________________________________________________________________ The ratio of the partial pressure of a component in a gaseous mixture to the total pressure of the mixture is called ________________________. Watch video tutorial on Blackboard Which component (H2, O2 or CO2) exerts the highest partial pressure in a gaseous mixture made of 0.50 mol H2, 0.49 mol O2, and 0.48 mol CO2? (ans: H2) Which of the following mixtures exerts the highest total pressure in 5.0‐L container? (a) 0.5 mol H2 + 0.6 mol N2 + 0.4 mol Cl2 (b) 0.7 mol H2 + 0.6 mol O2 + 0.1 mol N2 (c) 0.6 mol H2 + 0.3 mol Ar + 0.7 mol He (ans: c) A 25.0‐L cylinder contains 3.00 g of hydrogen gas and 14.0 g of nitrogen gas at 25.0oC. Calculate the mole fraction of each gas: (ans: XH2 = 0.75 and XO2 =0.25) Calculate the partial pressure of each gas: (ans: PH2= 1.47 atm and PO2= 0.489 atm) End of Chapter Practice Problems Tro First Edition: #61, 63, 65 Tro Second Edition: #65, 67, 69 answers are located in Appendix III of the textbook Take the Quiz on Blackboard 2 ...
