K _ c for the reaction A ₂( ~g ) T ( ~K ) B ₂( ~g ) is 39.0. In a closed one litre flask, one mole of A ₂( ~g ) was heated to T ( K ) . What are the concentrations of A ₂( ~g ) and B ₂( ~g ) (in mol ⁻¹ ) respectively at equilibrium?
Options
- A0.025,0.975
- B0.975,0.025
- C0.05,0.95
- D0.02,0.98
Correct answer
A. 0.025,0.975
Step-by-step solution
aligned & Initial & array l Equilibrium K _ c = [ B ₂ ] [ A ₂ ] 39= [ x 1 ] [ 1- x 1 ] or, 39-39 x = x 40 x =39 x = 39 40 x =0.975 Concentration of B ₂=0.975 Concentration of A ₂=1-0.975 array - 1-0.025 aligned
