Chemistry - Chemical Equilibrium Question with Solution | TestHub

The reaction, $$2\mathrm{A}(\mathrm{g})+\mathrm{B}(\mathrm{g})\rightleftharpoons 3\mathrm{C}(\mathrm{g})+\mathrm{D}(\mathrm{g})$$ is begun with the concentrations of $A$ and $B$ both at an initial value of $1.00\mathrm{M}$. When equilibrium is reached, the concentration of $D$ is measured and found to be $0.25\mathrm{M}$. The value for the equilibrium constant for this reaction is given by the expression
