1. Predict the shift in the following equilibrium system resulting from each of the following changes (5 marks (C)) 4 \mathrm{HCl}_{(\mathrm{g})}+\mathrm{O}_{2(\mathrm{~g})} \leftrightarrow 2 \mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})}+2 \mathrm{Cl}_{2(\mathrm{~g})}+113 \mathrm{KJ} (a) an increase

in the temperature of the system (b) a decrease in the volume of the container (c) an increase in the concentration of oxygen (d) the addition of a catalyst (e) addition of Ne(g) at constant pressure
