The value of K C for the equilibrium reaction: CO 2 ( g ) + C ( s ) ⇌ 2 CO ( g ) at T ( K ) is 0 . 036 . If the equilibrium concentration of CO 2 ( g ) is 0 . 004 M , the concentration of CO ( g ) in molL - 1 is
Options
- A3 . 6 × 10 - 2
- B2 . 0 × 10 - 2
- C1 . 2 × 10 - 2
- D1 . 2 × 10 - 3
Correct answer
C. 1 . 2 × 10 - 2
Step-by-step solution
As equilibrium constant can be written as: K c = C O 2 C O 2 0 . 036 = C O 2 0 . 004 C O = 1 . 2 × 10 - 2
