please solve both of these for thumbs up

The two alternative chair conformations of cis-1-cyano-2-methylcyclohexane differ in their Gbbs free energy. Using the data for G (Axeal-Equatorial) for monosubstituted cyclohexanes at room temperature (25C) : a. Calculate the absolute value of the dfference in the Gibbs free energy betwoen the aitemative chair conformations. b. Which group in this compound is in axal position in the energotically preferred char conformation? Foliowina are the altemative chair contormations for trans-1,4-dimethylcyclohexane: Using the data for G for monosubsututed cyclohexanes at room temperature (25C) and the representative value" for the gauche interaction of two equatarialy positioned wbstituents in the 1,2 position: a) Calculate the difference in the Gibbs tree energy between the second and frist conformation includrg the agebraic sen, b) Given your value in (a), cacuate the percent of the chair, indicated as B, presented in an equabrium mature of the corformers at 2.5 'C. The actual value will depend on the substituents. The values of the gas constant ard the terperature for 25C are 8.314x1mol1 and 298K tespectuely
