For the reaction:
, the equilibrium constant at 4000 k and 1.0 bar is 2.56 . When the pressure is increased by 4 -fold, the equilibrium constant.
Increase by a factor of 1.86
Decreases by a factor of 1.86
Remains same
Increases by a factor of 8
By Increased in pressure equilibrium constant doesn't changable equilibrium constant only depends on temp change.
