Test your understanding of this lesson Concept of enthalpy and some problems based on enthalpy:-

1)
For exothermic reaction
  • dH=0
  • dH=+ c
  • dH=-
  • none
2)
For endothermic reaction
  • dH=+
  • dH=0
  • dH=-
  • none
3)
H is an
  • extensive property of the system
  • intensive property of the system
  • none
  • both (a) & (b) property of the system
4)
dH is a state function
  • always truen't say
