Question
(7) Le Chatelier's Principle
Is the statement true or false, with respect to the specified reaction in each case?
If a vessel, containing an equilbrium mixture of these gases, is pressurized by adding helium gas, then the equilibrium position will shift to the left.
If an equilbrium mixture of these gases is released into a vessel of larger volume, then the equilibrium position will not shift.
If KOH is dissolved in this solution, then the equilibrium position will not shift. (Note that Fe(OH)3 is insoluble.)
If sulfur dioxide gas is removed from an equilbrium mixture of these gases, then the equilibrium position will shift to the right.
If the temperature is decreased, then the equilibrium constant for this reaction equation will increase.
a) H2(g) + F2(g) 2HF(g)Explanation / Answer
Ans 7 :
According to Le chatelier's principle , a system at equillibrium tries to re-estabilish its equillibrium , when any change in the reaction conditions is made.
So here :
a) False
No change will be observed , since the pressure is same on both the sides.
b) false
The large volume accounts to decrease in pressure , so the equillibrium shifts to left.
c) false
equillibrium will shift , as KOH forms insoluble Fe(OH)3 in the solution , that decreases the Fe3+ content.
d) True
SO2 is product , so when its concentration is decreased , the equillibrium shifts to right , to produce more of it.
e) True
SInce the heat is released in the product side , low temperature will favour the forward direction.
