a. The addition of Cl(g) to the system will shift the reaction right, towards the products, to counteract the increase in the concentration of Cl(g).
b. The removal of TiCl(k) from the system will shift the reaction right, towards the products, to counteract the decrease in the concentration of TiCl(k).
c. Decreasing the temperature of the container will shift the reaction to the right, towards the products, to counteract the decrease in kinetic energy of the system.
d. Increasing the pressure of the container will shift the reaction to the left, towards the reactants, to counteract the increase in pressure caused by the decrease in volume.
e. Adding Ti(s) to the system will not cause a shift in the reaction because Ti(s) is not involved in the reaction.
