CH4+Cl2--------CH3Cl+HCl
CH3Cl+Cl2-----------CH2Cl2+HCl
CH2Cl2+Cl2----------CHCl3+HCl
CHCl3+Cl2------------CCl4+HCl
CH3Cl、CH2Cl2、CHCl3、CCl4各0.25mol则耗氯气为0.25+0.25X2+0.25X3+0.25X4=2.5mol
CH4+Cl2--------CH3Cl+HCl
CH3Cl+Cl2-----------CH2Cl2+HCl
CH2Cl2+Cl2----------CHCl3+HCl
CHCl3+Cl2------------CCl4+HCl
CH3Cl、CH2Cl2、CHCl3、CCl4各0.25mol则耗氯气为0.25+0.25X2+0.25X3+0.25X4=2.5mol
