K _ c for the following reaction is 99.0 A ₂( ~g ) T ( ~K ) B ₂( ~g ) In a one litre flask, 2 moles of A ₂ was heated to T ( K ) and the above equilibrium is reached. The concentrations at equilibrium of A ₂ and B ₂ are C ₁ ( ~A ₂ ) and C ₂ ( ~B ₂ ) respectively. Now, one mole of A ₂ was added to flask and heated to T ( K ) to establish the equilibrium again. The concentrations of A ₂ and B ₂ are C ₃ ( ~A ₂ ) and C ₄

Options

  1. A1.98
  2. B0.01
  3. C0.03
  4. D2.97

Correct answer

C. 0.03

Step-by-step solution

Given, K _ c =99.0 On adding one mole of A ₂ Hence, C ₃ ( ~A ₂ )=0.03 moles.
