1mol ........1mol
CH4 + Cl2------> CH3Cl + HCl........x1a
CH4 + 2cL2-----> CH2Cl2 + 2HCl.....x2a
Cl2.......................>...Cl2...................x5a
SE da n= 10 mol CH3CL
10=1a mol
in prima reactie intra 1a=10mol Cl2
in a doua reactie intra 4a= 40mol Cl2
raman nereactionati 5a=50mol Cl2 TOTAL 100mol Cl2
