What will happen if 2.3 L of nitrogen gas is added to a 5 L flask that contains a mixture of monoxide, oxygen, and carbon dioxide? ll happen if 2.3 L of nitrogen gas is added to a 5 L flask that contains a mixture of carbon O shift toward the products O not shift O shift toward the reactants The equilibrium will O increases the partial pressures of the products. does not change the partial pressures of the gases. increases the partial pressures of the reactants. because the addition of the nitrogen D

Explanation / Answer

Answer is equilibrium shift towards the reactant.

When an inert gas is added to the system in equilibrium at constant pressure, then the total volume will increase. Hence, the number of moles per unit volume of various reactants and products will decrease. Hence, the equilibrium will shift towards the direction in which there is increase in number of moles of gases.

As the number of moles are more on the side of reactant, so equilbrium will shift to the reactant side.

As we add nitrogen partial pressure on product side increases

Before, Ptotal= Preactant+ Pproducts

After, Ptotal= Preactant+ Pproducts + Pgas

Partial pressures of reactants and products must decrease in order to keep total pressure constant. So, the equilbrium will shift to reactant side
