  5. Enthalpy is negative for exothermic process and state function represents physical state.Entropy tends towards increase and does not remain constant.I hope this will be helpful to the visitors in future

  12. There are some mistakes in these questions . In exothermic reaction , enthalpy is negative and value of Delta H is less than zero ,so heat is released . its sign is negative then. Secondly Entropy is the measure of disorder of system and its increasing gradually (not constant) which will result in heat death after million of years.
