Answer to Question #207737 in Physical Chemistry for Aditya Venkatesh A

Question

A mixture of gases is at equilibrium: 2 SO3 (g) → 2 SO2 (g) + O2 (g) ∆H = 197.78 kJ (a) Does the equilibrium shift to the left or to the right when some SO3 (g) is added to the reaction mixture? (b) Does the equilibrium shift to the left or to the right when some SO2 (g) is added to the reaction mixture? (c) In which direction does the equilibrium shift as the temperature is lowered? (d) In which direction does the equilibrium shift as pressure is applied to the system?

Answer 1

 a) The equillibrium shift to the right

b) The equillibrium shift to the left

C) reducing the temperature  will shift the equilibrium to the left

D) will shift to left
