The equilibrium system between hydrogen gas, bromine gas, and hydrogen bromide gas is given. \[ \mathrm{H}_{2}(\mathrm{~g})+\mathrm{Br}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HBr}(\mathrm{g}) \] Write the balanced chemical equation for the reverse reaction. Include physical states for all species. chemical equation: Write the equilibrium constant expression for the reaction \[ \mathrm{A}(\mathrm{s})+3 \mathrm{~B}(\mathrm{l}) \rightleftharpoons 2 \mathrm{C}(\mathrm{aq})+\mathrm{D}(\mathrm{aq}) \] in terms of \( [A],[B],[C] \), and \( [D] \) as needed. \[ K_{c q}= \]
