Imagine that the staggered and eclipsed conformers of a small, saturated hydrocarbon are separated in energy by 1.5 kcal/mol. Given this information, what fraction of the molecules would be in the staggered conformation at any given instant? Assume that the sample is at thermal equilibrium at 25 °C, and enter your answer to the nearest hundredth. For example, if the fraction you determined was 1/2, you would enter 0.50 as your answer. Hint: the gas constant, R, equals 1.987 cal/K·mol and T in Kelvin equals the temperature in Celsius + 273; also, assume that all the molecules are either staggered or eclipsed. |

Question
Imagine that the staggered and eclipsed conformers of a small, saturated
hydrocarbon are separated in energy by 1.5 kcal/mol. Given this information,
what fraction of the molecules would be in the staggered conformation at any
given instant? Assume that the sample is at thermal equilibrium at 25 °C, and
enter your answer to the nearest hundredth. For example, if the fraction you
determined was 1/2, you would enter 0.50 as your answer. Hint: the gas
constant, R, equals 1.987 cal/K-mol and T in Kelvin equals the temperature in
Celsius +273; also, assume that all the molecules are either staggered or eclipsed.
