Consider the reaction 2 SO _ 2( ~g ) + O _ 2( ~g ) 2 SO _ 3( ~g ) + Heat What will happen if 0.5 mole of Helium gas is introduced into the vessel so that the temperature and pressure remain constant?

Options

  1. Athe equilibrium concentration of SO ₂ increases
  2. Bthe equilibrium will shift to left
  3. Cthe equilibrium concentration of O ₂ increases
  4. Dequilibrium constant will increase

Correct answer

C. the equilibrium concentration of O ₂ increases

Step-by-step solution

At constant pressure, the addition of inert gas shifts the equilibrium towards larger no. of moles.
