Is the statement true or false, with respect to the specified reaction in each case?

•

(A) H2(g) + F2(g) 2HF(g)

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.    

•

(B) N2(g) + 3H2(g)  2NH3(g)

If an equilbrium mixture of these gases is released into a vessel of larger volume, then the equilibrium position will shift to the right.    

•

(C) Fe3+(aq) + SCN-(aq) FeSCN2+(aq)

If KOH is dissolved in this solution, then the equilibrium position will shift to the right. (Note that Fe(OH)3 is insoluble.)   

•

(D) 2SO3(g) 2SO2(g) + O2(g)

If sulfur dioxide gas is added to an equilbrium mixture of these gases, then the equilibrium position will shift to the right.    

•

(E) 2SO3(g) 2SO2(g) + O2(g) (Endothermic)If the temperature is decreased, then the equilibrium constant for this reaction equation will remain the same.    

My answers are

(A) false

(B) true

(C) true

(D) false

(E) false

These are my answers to above question!
