Graphing Calculator Calculating the Gibbs-Energy Change The graphing calculator can run a program that calculates the Gibbs-energy change, given the temperature, T, change in enthalpy, H, and change in entropy, S. Given that the temperature is 298 K, the change in enthalpy is 131.3 kJ/mol, and the change in entropy is 0.134 kJ/(molK), you can calculate Gibbs-energy change in kilojoules per mole.Then use the program to make calculations. Go to Appendix C. If you are using a TI-83 Plus, you can download the program ENERGY data and run the application as directed. If you are using another calculator, your teacher will provide you with keystrokes and data sets to use. After you have run the program, answer the following questions. a. What is the Gibbs-energy change given a temperature of 300 K, a change in enthalpy of 132 kJ/mol, and a change in entropy of 0.086 kJ/(molK)? b. What is the Gibbs-energy change given a temperature of 288 K, a change in enthalpy of 115 kJ/mol, and a change in entropy of 0.113 kJ/(molK)? c. What is the Gibbs-energy change given a temperature of 298 K, a change in enthalpy of 181 kJ/mol, and a change in entropy of 0.135 kJ/(molK)?
