Chapter 2, Problem 9TYPSS

Would you expect the products of an endergonic reaction to be more stable than the reactants? a. yes because the energy of activation is negative in these cases. b. no because the products have higher potential energy which result in less stable molecules. c. no because the energy of activation is always lower in an endergonic reaction, which results in a less stable product. d. yes because the products have higher free energy and therefore require more energy to break bonds.

For this reaction: 6CO2 + 6H2O → C6H12O6 + 6O2, the products have 2760 kJ/mole more free energy than the reactants. So, which of the following statements best describes the reaction? a The reaction is endergonic because it converts molecules with less free energy to those with more free energy. b The reaction is exergonic because it converts molecules with less free energy to those with more free energy. c The reaction is exergonic because it converts molecules with more free energy to those with less free energy d The reaction is endergonic because it converts molecules with more free energy to those with less free energy.

What statements concerning free energy change are true or false? a. Free energy change is a measure of the rate of a reaction. b. Free energy change is a measure of the maximum amount of work available from a reaction. c. Free energy change is a constant for a reaction under any conditions. d. Free energy is related to the equilibrium constant for a specific reaction. e. Free energy change is equal to zero at equilibrium
