### Question 11.13

Posted:

**Sun Jul 23, 2017 5:54 pm**"Write the reaction quotient Q for:

(a) 2 BCl3(g) + 2 Hg (l) --> B2Cl4 (s) + Hg2Cl2 (s)

(b) P4S10 (s) + 16 H2O (l) --> 4 H3PO4 (aq) + 10 H2S (aq)

(c) Br2 (g) + 3 F2 (g) --> 2 BrF3 (g)"

As I understand, Q is equal to [products]/[reactants]. However, the answer for (a) is 1/PBCl3^2, and I am not sure how to get that answer. I feel like I'm overthinking this one, but if anyone could help me out, that would be great. Thanks!
