  • How does entropy change with increase in temperature?
  • True or False. Both steam and water contain two atoms of hydrogen and one atom of oxygen, but the entropy
    value of steam is greater than that of water.
  • Entropy value will be highest in:
  • In the case of a reversible reaction, if the forward reaction is spontaneous, the reverse reaction is
    _____.
  • Free energy changes are measured in what units?
  • Tabulated values for ∆H ̊ and ∆S ̊ are very temperature dependent and so the free energy change for a reaction at any temperature other than 25 ̊C cannot be calculated.
  • True or False. For a spontaneous chemical change, the free energy is zero.
  •  is a measure of the degree of randomness or disorder of a system.
  • The entropy of a room that has been recently cleaned and organized is?
