Chem 142 Summer 2011 Page 1 of 4 Name ________________________________________ Section ________________ Worksheet 6: Gases Ideal Gas Law: PV=nRT 1. The major industrial source of hydrogen gas is the reaction of methane with water at high temperatures (800-1000 ° C) and pressures (10-50 atm) in the presence of the metallic catalyst (often nickel): __ CH 4 (g) + __ H 2 O (g) __ CO (g) + __ H 2 (g) 2.00 L of CH 4 (g) and 3.00 L of H 2 O (g) at 25.0 ° C and 1.00 atm are placed in a 1.00 L rigid reaction vessel and heated to 1000.0 ° C and held constant. a. Do you expect the new pressure or be higher or lower? What is the pressure within the reaction vessel? Is this pressure sufficient for the reaction to proceed? b. Assuming the reaction goes to completion, how many moles of H 2 (g) will be produced by this reaction? c. What will the partial pressure of each gas remaining in the vessel be? What is the total pressure within the reaction vessel? 2. Ammonia, a very important fertilizer and a starting material for the industrial synthesis of nitric acid, is made by combining nitrogen from the air with hydrogen according to the equation: __ N 2 (g) + __ H 2 (g) __ NH 3 (g) This reaction (the Haber process) for manufacturing ammonia is carried out at a pressure of about 250 atm and a temperature of approximately 400 ° C. The H
