Question: The equation relating Go to K contains a temperature term. Refer to your answer to Problem 44 (a) to calculate the answers to the questions

The equation relating △Go to K contains a temperature term. Refer to your answer to Problem 44 (a) to calculate the answers to the questions that follow. You will need to know that △So for the formation of the more stable conformer of 2-methylbutane from the next most stable conformer is +1.4 cal K-l mol-1. (a) Calculate the enthalpy difference (△Ho) between these two conformers from the equation △Go = △H° - T△S°. How well does this agree with the △H° calculated from the number of gauche interactions in each conformer? (b) Assuming that △H° and △So do not change with temperature, calculate △G° between these two conformations at the following three temperatures: -250°C; - 100°C; +500°C. (c) Calculate K for these two conformations at the same three temperatures.
