Answer: Displacement reaction
Step-by-step explanation:
The reaction
F2(g) + 2NaCl(s) --> 2NaF(s) + Cl2(g) is a displacement reaction because fluorine F2 displaced chlorine from the solution of its salt due to the relatively higher reactive potential of fluorine compared to chlorine among electronegative elements.
Thus, a salt of fluorine, NaF is formed while chlorine is displaced to just chlorine gas
