Determine whether each of the following statements about the thermodynamic functions are True or False as they apply to chemical reactions. True False Spontaneity is increased by positive entropy changes. True False All spontaneous chemical reactions have negative heats of reaction. True False Spontaneity is increased by negative enthalpy changes. True False Entropy and enthalpy are multiplied in the Gibbs free energy. True False The heat of reaction at constant pressure is always equal to the work done by the reaction.

Determine whether each of the following statements about the thermodynamic functions are True or False as they apply to chemical reactions. All spontaneous chemical reactions have no heat of reaction. Entropy and temperature are multiplied in the Gibbs free energy. Spontaneity is decreased by negative entropy changes. Spontaneity is decreased by positive enthalpy changes. The heat of reaction at constant volume is always equal to the change in the enthalpy. I put FALSE, FALSE, TRUE, FALSE, TRUE.

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.

Which of the following statements about activation energy is correct? Reactions may have negative activation energies. It is the minimum energy required for colliding reacting particles to react. It is the maximum energy a reacting molecule may possess. In general, reactions with higher activation energies are faster.

Mark all the statements that are TRUE. You may select one or more. a-Spontaneity for a reaction at 45C depends on ∆G not ∆G standard b-A large, negative ∆G means that the reaction is fast and spontaneous c- ∆G° is zero at equilibrium d- Increasing the concentration of reactants decrease the value of ∆G e-∆G standard is always the same for a given reaction I selected everything but c- ∆G° is zero at equilibrium. My answer was incorrect.
