Multiple Choice Options

  • A ΔSsystem+ΔSsurroundings>0\Delta S_{system}+\Delta S_{surroundings}>0
  • B ΔSsystem−ΔSsurroundings>0\Delta S_{system}-\Delta S_{surroundings}>0
  • C ΔSsystem>0\Delta S_{system}>0 only
  • D ΔSsurroundings>0\Delta S_{surroundings}>0 only

Step-by-Step Verified Solution

For the reaction to be spontaneous, the total entropy of system and universe increases i.e., _ S s y s t e m + _ S s u r r o u n d i n g s > 0
