The correct answer of equilibrium concentration of BrCl is 0.2292 M.
The balanced chemical equation:
Br2(g) + Cl2(g) = 2BrCl(g)
[Br2] = [Cl2] = (0.2 - x) M
[BrCl] = (2x) M
7.20 = [2x / (0.2 - x)]2
2.6833 = 2x / (0.2-x)
2.6833 × (0.2 - x) = 2x
0.53666 - 2.6833x = 2x
0.53666 = 4.6833x
x = 0.1146
[Br2] = [Cl2] = 0.2 - x = 0.2 - 0.1146 = 0.0854 M
[BrCl] = 2x = (2 × 0.1146) = 0.2292 M
[BrCl] = 0.2292 M

What is equilibrium concentration?</h3>
A chemical reaction is considered to be in a state of chemical equilibrium when both the reactants and the products are in a concentration that does not change over time any more. The forward response rate and the backward reaction rate are equal in this condition. You can determine the equilibrium concentration for a reaction if you know the starting concentrations of the constituent chemicals.

Explanation:
Besides water what is the product of a Neutralization Reaction between HNO3 and Al(OH)3
AINO3
Given 3.72 g of P and 21.28g of Cl, converting these to moles: ( 3.72 g P)(mol P/30.97 g P) = 0.12 mol P (21.28 g Cl)(mol Cl/35.45 g Cl) = 0.60 mol Cl P:Cl = 0.12/0.60, therefore P: Cl =1/5 Therefore, PCl5 hope it helps
