Question

Le Chatelier's Principle: When the system, at equibrium, is stressed as given below, which direction will the reaction proceed? Mark your answers on the front page. 14. Cool reaction flask. (b) (a) (c) Equilibrium will not shift. +- 15. Add H2) (a) (b) (c) Equilibrium will not shift. 16. Reduce the volume of the reaction vessel. (a) (b) (c) Equilibrium will not shift. 17. Spray water into the reaction vessel. (NH, (&) is far more soluble in water than N2(g) or H2(8).) (a) (b) (c) Equilibrunn will not shift. 18. Add helium gas. (a) (b) (c) Equilibrium will not shift.

Explanation / Answer

a) reaction will shift towards left as it is an endothermic reaction , so cooling will cause the reaction to shift towards left using le chatiliar principle

b) adding H2 will shift the reaction to right side , as more product formatio will be favoured.

c)reduction will shift the reaction towards more volume side , that is the reactant side in this case
