H2(g)+F2(g)?2HF(g)?H=?537kJ

C(s)+2F2(g)?CF4(g)?H=?680kJ 2

C(s)+2H2(g)?C2H4(g)?H=+52.3kJ

2H2(g)+2F2(g)?4HF(g)    ?H=?1074kJ

2C(s)+4F2(g)?2CF4(g)    ?H=?1360kJ

--------------------------------------------------------------------------------

2C(s) + 2H2(g) +6F2(g) --------> 2CF4(g) + 4HF(g) ?H = -2434Kj

2C(s)+2H2(g )          ?C2H4(g)                                     ?H=+52.3kJ      substract

(-)        (-)                   (-)                                                        (-)

------------------------------------------------------------------------------------

C2H4(g)+6F2(g)?2CF4(g)+4HF(g)                           ?H    = -2486
