Question
Iodine and bromine react to give iodine monobromide, IBr.

The chemical equation for the reaction is:

\[ I_2(g) + Br_2(g) \rightleftharpoons 2IBr(g) \]

**Problem Statement:**

What is the equilibrium composition of a mixture at 139°C that initially contained \(2.10 \times 10^{-3}\) mol each of iodine and bromine in a 5.00 L vessel? The equilibrium constant \(K_c\) for this reaction at 139°C is 95.7.

**Concentration Calculations:**

- \([I_2]\) = ______ M
- \([Br_2]\) = ______ M
- \([IBr]\) = ______ M

Fill in the calculated equilibrium concentrations in the provided spaces.
