Question

the
ice\ table below shows the c and e in terms of x. calculate the \\(\text{br}_2\\) at equilibrium if \\(x = 0.28\\).

\

$$\begin{tabular}{|c|c|c|c|} \\hline r(eaction) & \\(\\text{h}_2\\text{ (g)} +\\) & \\(\\text{br}_2\\text{ (g)}\\) & \\(\ ightleftharpoons 2\\text{ hbr (g)}\\) \\\\ \\hline i(nitial) & 0.40 & 0.40 & 0.05 \\\\ \\hline c(hange) & - x & - x & + 2x \\\\ \\hline e(quilibrium) & 0.40 - x & 0.40 - x & 0.05 + 2x \\\\ \\hline \\end{tabular}$$

\\(\text{br}_2 = ?\text{ m}\\)

Explanation:

Identify the equilibrium expression

Using the RICE Table Calculations knowledge point

$$ [\text{Br}_2]_{\text{eq}} = 0.40 - x $$

Substitute the given value of x

Using the RICE Table Calculations knowledge point

$$
LATEXBLOCK0
$$

Answer:

The "RICE" table below shows the C and E in terms of x. Calculate the \([\text{Br}_2]\) at equilibrium if \(x = 0.28\).
