Â Â Â Â Â Â Â Â Â Â Â Â B.Â Â Â Â Â Â Â Â Addinga catalyst
Â Â Â Â Â Â Â Â Â Â Â Â C.Â Â Â Â Â Â Â Â Increasingthe pressure
Â Â Â Â Â Â Â Â Â Â Â Â D.Â Â Â Â Â Â Â Â Lowingthe temperature
13.Â Â Â Â Â Â Â Â Â Considerthe following equilibrium system: CaCO_3(s)Â Ââ‡„CaO_(s) +Â Â CO_2(g)
Â Â Â Â Â Â Â Â Â Â Â Â Whichone of the following changes would cause the above system to shiftleft?
Â Â Â Â Â Â Â Â Â Â Â Â A.Â Â Â Â Â Â Â Â Addmore CaO
Â Â Â Â Â Â Â Â Â Â Â Â B.Â Â Â Â Â Â Â Â RemoveCaCO₃
Â Â Â Â Â Â Â Â Â Â Â Â C.Â Â Â Â Â Â Â Â Increasepressure
Â Â Â Â Â Â Â Â Â Â Â Â D.Â Â Â Â Â Â Â Â RemoveCO2
14.Â Â Â Â Â Â Â Â Â Considerthe following equilibrium:SO₂Cl₂₍_g)Â Â+Â Â energyÂ Â â‡„Â Â SO_2(g)Â Â+Â Â Cl_2(g)
Â Â Â Â Â Â Â Â Â Â Â Â Whenthe temperature is decreased, the equilibrium shifts
Â Â Â Â Â Â Â Â Â Â Â Â A.Â Â Â Â Â Â Â Â Leftand [ SO₂Cl₂ ] increases
Â Â Â Â Â Â Â Â Â Â Â Â B.Â Â Â Â Â Â Â Â Leftand [ SO₂Cl₂ ] decreases
Â Â Â Â Â Â Â Â Â Â Â Â C.Â Â Â Â Â Â Â Â Rightand [ SO₂Cl₂ ] increases
Â Â Â Â Â Â Â Â Â Â Â Â D.Â Â Â Â Â Â Â Â Rightand [ SO₂Cl₂ ] increases
15.Â Â Â Â Â Â Â Â Consider thefollowing equilibrium system:CO_{2(g)Â Â Â}+Â Â H_2(g)Â Ââ‡„Â Â CO_(g)Â Â +Â Â H₂O_(g)
Â Â Â Â Â Â Â Â Â Â Â Â Whichof the following, when added to the system above, would result in anet decrease in [H₂O]?
Â Â Â Â Â Â Â Â Â Â Â Â A.CO₂
Â Â Â Â Â Â Â Â Â Â Â Â B.H₂
Â Â Â Â Â Â Â Â Â Â Â Â C.CO
Â Â Â Â Â Â Â Â Â Â Â Â D.H₂
16.Â Â Â Â Â Â Â Â Â Considerthe following equilibrium:C_(s)Â Â +Â Â 2H_2(g)Â Ââ‡„CH_4(g)Â Â+Â Â 74 kJ
Â Â Â Â Â Â Â Â Â Â Â Â Whena small amount of solid C is added to the system
Â Â Â Â Â Â Â Â Â Â Â Â A.[H₂] decreases
Â Â Â Â Â Â Â Â Â Â Â Â B.[CH₄] increases
Â Â Â Â Â Â Â Â Â Â Â Â C.The temperature increases
Â Â Â Â Â Â Â Â Â Â Â Â D.All concentrations remain constant
17.Â Â Â Â Â Â Â Â Â Considerthe following equilibrium:2NO₍_g)Â Â +Â Â Cl_2(g)Â Ââ‡„Â Â 2NOCl_(g)
Â Â Â Â Â Â Â Â Â Â Â Â Atconstant temperature and volume, Cl₂ is added to theabove equilibriumÂ Â Â system. As equilibriumre-establishes, the
Â Â Â Â Â Â Â Â Â Â Â Â A.[NOCl] will decrease
Â Â Â Â Â Â Â Â Â Â Â Â B.The temperature increases
Â Â Â Â Â Â Â Â Â Â Â Â C.[NO] will increase
Â Â Â Â Â Â Â Â Â Â Â Â D.[NOCl] will increase

According to LeChatlier Principle If a reaction At equilibrium is subjected to a change in Any of the reaction condition ie Temperature Pressure Concentration or Volume then the reaction will shift in a direction to undo the effect of change 12 Reaction Is 2SO2gO2g2SO3gE A O2 is added If we add more O2 to reaction then the concentration of O2 increases and to undo this effect ie to decrease its concentration reaction will shift in a direction in which it is consumed which is the forward direction Hence reaction will shift right B Adding a Catalyst If we add a catalyst in a reaction at equilibrium then it has no effect on it because Catalyst is added in a reaction to increase its rate but it See Answer
