Question

CO(g) + Cl2(g) ------------------- COCl2(g)                     Delta H = - 109.6KJ

a) In a given system , the forword reaction is exothermic reaction because Delta H is negative sign.

According to Lechatelier principle the exothermic reactions are favoured at low temperature.But the temperature is increases on equilibrium system endothermic reaction is favoured, i.e backword reaction is favoured.

So temperature is increases on equilibrium system , the equilibrium shift towords to the left side.

b) When the volume of the system is increased , then the equilibrium is shifted towords to the number of moles decreased side,

In a given reaction the number of moles of decreased in the forword direction ( 1+1=1).

Hence the equilibrium is shifted towords to the right side.

Explanation / Answer

15) Consider the following equilibrium co (g) + c12 (g) -- COc12 (g) H= -109.6 kJ In what direction will the equilibrium shift when each of the following changes is made to the system? a) The temperature of the system is increased b) The volume of the system is increased.
