What is the mass-action expression, Qp, for the following reaction? SbF5(g) + 4Cl2(g) SbCl3(g) + 5ClF(g)?

Question

A. (PCl2)(PSbF5)

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

(PSbCl3)(PClF)

B. (PCl2)4(PscF5)

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

P(SbCl3)(PClF)5

C. (PSbCl3)(PClF)

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

(PCl2)(PSbF5)

D. (PSbcl3)(PClF)5

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

(PPcl2)4(PsbF5)

e. None of these is the correct mass-action expression

Answer 1

D.

Qp = {P(SbCl3) x PClF)^5} / {P(SbF5) x P(Cl2)^4}
