Question 3 1 pts Consider the reaction at equilibrium: PC15(8) PC13(8)+ Cl2(9) Predict whether the reaction will shift to the left, shift to the right, or remain unchanged after each disturbance. (a) removing Cla(s) makes the equilibrium shift to the right (b) adding a calalyst makes the equilibrium shift to the right (c) increasing the volume of the container makes the equilibrium Select) + (d) adding an inert gas, He, makes the equilibrium (Select]
