Unformatted text preview: 1. Check all of the following statements that are true: The energy change of the universe for any spontaneous process is always positive The equilibrium constant is always equal to one for any system at equilibrium None of these statements are true The free energy change for any spontaneous process is always positive The entropy change of the universe for any spontaneous process is always positive The equilibrium constant is always greater than one for an extensive reaction Work is always equal to heat for a reversible reaction 2. Compare the reaction energy diagrams for the three gas phase reactions shown below 1) A 2 + B AB + A 2) A 2 + C AC + A 3) A 2 + D AD + A Assume that steric factors are all comparable and that entropy is not important in the following. Specify a reaction with its number (1,2, or 3) . The forward reaction with the largest rate constant is 1 The reaction with largest equilibrium constant is 3 The reaction whose equilibrium constant increases the most with an increase in temperature is 2...
