Solid ammonium carbomate, NH_4CO_2NH_2(s), dissociates into ammonia and carbon dioxide when it evaporates as shown by NH_4CO_2NH_2(s)hArr2NH_3(g)+CO_2(g) At 25^@C, the total pressure of the gases in equilibrium with the solid is 0.116 atm.If 0.1 atm of CO_2 is introduced after equilibrium is reached then :

Answer»

Final PRESSURE of `CO_2` will be less than 0.1 atm
Final pressure of `CO_2` will be more than 0.1 atm
Pressure of `NH_3` will DECREASE due to addition of `CO_2`
Pressure of `NH_3` will increase due to addition of `CO_2`

SOLUTION :The pressure of `NH_3` will decrease due to addition of `CO_2` (BACKWARD, shifting Le-chatelies's PRINCIPLE).The pressure of `CO_2` will be more than 0.1 atm
