6. In a reaction where there is an increase in the number of gaseous molecules, entropy

  • Decreases
  • Increases
  • ΔSºreaction = ΣSº(products) - ΣSº(reactants)

7. If a change makes a system more random ΔH is positive, and if a change makes a system more ordered, ΔS is

  • Negative
  • ΔSºreaction = ΣSº(products) - ΣSº(reactants)

8. The free energy change ΔG is

  • The balance between enthalpy, entropy, and temperature for a process: ΔG = ΔH - TΔS
  • The entropy change that accompanies a reaction in the molar quantities as expressed in a chemical equation under standard conditions, all in standard states

9. In calculations concerning ΔG= ΔH - TΔS entropy is worked out using K

  • To convert C to K add 273 and the opposite to convert K to C
  • The entropy change that accompanies a reaction in the molar quantities as expressed in a chemical equation under standard conditions, all in standard states

10. Standard entropy change of reaction, ΔSº, is

  • The entropy change that accompanies a reaction in the molar quantities as expressed in a chemical equation under standard conditions, all in standard states
  • S is always a positive number

11. In calculations concerning ΔG= ΔH - TΔS 1, units must be the same for kJ/J

  • The units need to be the same, to convert ΔS to kJ K^-1 mol^-1 /1000
  • TΔS

12. The more disorder there is in the system, the

  • S is always a positive number
  • Higher the entropy
  • Decreases

13. Entropy ______ when a solid lattice dissolves

  • Increases
  • Decreases
  • S is always a positive number
