2. For he gas phase reaction l'he cquilibrium constanl is 4,00 at 120 ( . If you start with I.OO bar oflxth ethvl acetate and v、ater "1 J 10.0-1.container, what is the extent of the eaction at equilibri? 3. Calciu oxide (limestone) could e obtained rot tmal decompsition reacton of cal w carhonate. The decomposition reaction was occured 2nd AG (a) Deternihev te eqilibriu constant for this reaction? (b) What happens if temperature is ncreased or decreased? (c) How the effects forte value oeqilibrium constant? -13.8 J

Answer 1

Answer:

2. the value of equilibrium constant is showing that the reaction is in equilibrium. on subjecting the reaction mixture at 1 bar and 10 L container will change nothing and the system will remain at equilibrium.

3. a) we are given with standard gibbs energy change and temperature at which it was subjected so to calculate equilibrium constant we have a relation-

  

RTlnK

where symbols have their usual meaning

on putting the value of givens we obtained K =3.97

b) since this decomposition is endothermic in nature, on increasing the temperature it will proceed the reaction in forward direction.

c) since equilibrium constant depends on the concentration of CO₂ it will go in forward direction on increasing the temperature as it would help to escape the container and disturbs the state of equilibrium.
