The chlorination of methane occurs in a number of steps that results in the formation of chloromethane and hydrogen chloride. The overall reaction is 2 CH, (g) + 3 C1, (g) 2 CH, CI(g) + 2 HCl(g) + 2C1-(g) Suppose that a chemist combines 327 mL of methane and 727 mL of chlorine at STP in a 2.00 L flask. The flask is then allowed to stand at 298 K. If the reaction reaches 85.2% completion, what is the total pressure in the flask? Ptotal = atm What is the partial pressure of CH ? , atm What is the partial pressure of C1,? PCI, atm What is the partial pressure of CH, Cl? PCH = atm What is the partial pressure of HCI? Phci = atm What is the partial pressure of Cl? Pa- = atm
