The standard free-energy difference between the two chair conformations of isopropylcyclohexane is 9.2 kJ mol-1 (2.2 kcal mol-1). What is the ratio of concentrations of the two conformations (axial and equatorial) at 25 °C? (Calculate the ratio as the conformation present in a higher concentration over the lower one.)
