Cyclohexane, C6H12, a hydrocarbon, can isomerize or change into methylcyclopentane, a compound of the same formula (C5H9CH3) but with a different molecular structure.
The equilibrium constant is 0.12 at 25°C. If you had originally placed 0.036 mol of cyclohexane in a 1.0 L flask, what would be the concentrations of cyclohexane and methylcyclopentane when equilibrium is established?
Is this Kc or Kp = 0.12? I will assume it is Kc.
What is the reaction for K. I will assume it is
cyclohexane ==> methyl cyclopentane
K = 0.12 = (mcyp)/(cyh)
Set up an ICE chart.
...........mcyh ==> mcyp
Substitute the equilibrium values into the Kc expression and solve for x.
