1. Mark with T (True) or F (False) (2 points each) • Joule Thompson experiment corresponds to process with constant enthalpy. . The state functions (U.H,G,A) act as thermodynamic potentials when represented as functions of their natural variables. • The Gibbs free energy is equal to the maximum PV work done by the system on the envi- ronment. . The standard enthalpy of formation for any...

8. Indicate whether the following statements are true or false: a. If the free energy,AG,ofareaction is negative, then the entropy,AS,must be positive b. Anendergonicreactionisone forwhichAGispositive. c. Increasing the temperature usually increases the rate of a chemical reaction because it increases rate of movement of molecules d. A reaction that releases heat (ΔH) is termed exothermic, while a reaction that releases free energy, Δ G, is termed exergonic e. The transition state of a reaction is always at a higher (unfavorable)...
