One mole of A ( g ) is heated to T ( K ) till the following equilibrium is obtained A ( g ) T ( K ) B ( g ) The equilibrium constant of this reaction is 10⁻¹ . After reaching the equilibrium, 0.5 moles of A ( g ) is added and heated. The equilibrium is again established. The value of [ A ] [ B ] is

Options

  1. A10⁻¹
  2. B10
  3. C10⁻²
  4. D100

Correct answer

B. 10

Step-by-step solution

K _ C = [ B ] [ A ] =10⁻¹ or 1 10 Since K _ C remains constant at a given temperature, the value of [ B ] [ A ] will still be the same. [ B ] [ A ] = 1 10 [ A ] [ B ] =10
