    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.
