hydrogen chloride gas reacts with oxygen gas to yield chlorine gas and water vapor in an equilibrium reaction. an experiment was performed in a closed vessel starting with a mixture of 0.50 M HCl and 0.050 M O2. the amount of chlorine was monitored until no change was observed. the final concentration of the chlorine was 0.048 M chlorine.

a) prepare an ICE table to answer the following:

b) what is the Keq for this reaction?

c) what are the equilibrium concentrations of all substances in the reaction?
