Question

Le Chatelier's Principle Is the statement true or false, with respect to the specified reaction in each case?

• 2SO3(g)= 2SO2(g) + O2(g) If a vessel, containing an equilbrium mixture of these gases, is pressurized by adding argon gas, then the equilibrium position will shift to the right.

• 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.

• Fe3+(aq) + SCN-(aq)= FeSCN2+(aq) If Fe(NO3)3 is dissolved in this solution, then the equilibrium position will shift to the left.

• H2(g) + I2(g)= 2HI(g) If iodine gas is removed from an equilbrium mixture of these gases, then the equilibrium position will not shift.

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

Explanation / Answer

Hi

2SO3(g)= 2SO2(g) + O2(g) If a vessel, containing an equilbrium mixture of these gases, is pressurized by adding argon gas, then the equilibrium position will shift to the right.- False, since the partial pressureof each gas will remain same.

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.- False, the equilibrium will shift to the left, since more moles will be created on left.

Fe3+(aq) + SCN-(aq)= FeSCN2+(aq) If Fe(NO3)3 is dissolved in this solution, then the equilibrium position will shift to the left.- False, there will be no change in equilibrium.

H2(g) + I2(g)= 2HI(g) If iodine gas is removed from an equilbrium mixture of these gases, then the equilibrium position will not shift.-False, the equilibrium will shift to left to create more I2.

2SO3(g)= 2SO2(g) + O2(g) (Endothermic) If the temperature is decreased, then the equilibrium constant for this reaction equation will remain the same.-False, the reaction will shift to left.

Thank you
