A reaction  is found to have a positive entropy change. The reaction will be

• possible at high temperature
  
  

• possible only at low temperature
• not possible at any temperature
• possible at any temperature

A thermodynamic state function is a quantity

• used to determine heat changes
• whose value is independent of path
• used to determine pressure volume work
• whose value depends on temperature only

• ∆T = 0
• ∆p = 0
• q = 0
• w = 0

• unity

• zero

• <0

• different for each element
