Cyclohexane, C 6 H 12 , a hydrocarbon, can isomerize or change into methylcyclopentane, a compound of the same formula (C 5 H 9 CH 3 ) but with a different molecular structure. sssss The equilibrium constant has been estimated to be 0.12 at 25 °C. If you had originally placed 0.045 mol of cyclohexane in a 2.8-L flask, what would be the concentrations of cyclohexane and methylcyclopentane when equilibrium is established?
