2CH4(g)+3Cl2(g)2CH3Cl(g)+2HCl(g)+2Cl(g) Suppose that a chemist combines 311mL of methane and 595mL of chlorine at STP in a 2.00L flask. The flask is then allowed to stand at 298K. If the reaction reaches 75.4% completion, what is the total pressure in the flask? What is the partial pressure of CH4 ? POt2= What is the parial pressure of Cl2 ? PCC2= What is the partial pressure of CH3Cl ? What is the parial preisure of HCl ? What is the partial pressure of Cl
