The decomposition of hydrogen iodide to hydrogen and iodine occurs by the reaction 2H1 (g) HH2 (g) + 12 (g)
Hydrogen iodide is placed in a container at 450°C an equilibrium mixture
contains 0.5 moles of hydrogen iodide. The equilibrium constant is 0.020
for the reaction. How many moles of iodine and hydrogen are present in
the equilibrium mixture?
