At a certain temerature, the gas difluorethyn is (C2F2) in (equilibrium/balance(I dont know how its called in english so i wrote both names)) with the gas hexafluorbenzeen (C6F6)

a) write the balanced (equilibrium) equation

b) give the equilibrium condition

Im not sure, but I have a certain feeling that equilibrium is the wrong term...for balanced in chemistry....
