2. In terms of the system - change in H > 0 - means...

  • That the system has gained energy (exothermic)
  • That the system has gained energy (endothermic)
  • That the system has lost energy (endothermic)
  • That the system has lost energy (exothermic)

3. Which of these is not a feature of spontaneous reaction?

  • An e.g osmosis, expansion of compressed gas
  • During Spontaneous process - the total energy increases
  • When spontaneous reaction proceeds - energy is released
  • The reversion of the sponstaneous process is unreal
  • Spontaneous reaction proceeds until equilibrium is reached

4. Which of these systems is incorrect?

  • Closed system - Matter and energy not exchanged with the surroundings
  • Open System - exchange of matter and energy with the surroundings
  • Isolated system - Matter and energy not exchanged with the surroundings

5. Which of these statements is not related to entropy

  • Change in S> change in H / T
  • At equlibrium entropy always decreases in an isolated sytsem
  • Inequality of Clausius - (when energy changes form- some part is lost as entropy)
  • Entropy never decreases in an isolated system
  • An Isolated system spontaneously passes to the most probable state (a macroscopic state with the highest no. of microscopic state)
  • Entropy increases until equilibrium is reached in an isolated system
  • S= Kb ln W
