  1. competent

  2. In MCQ 4, all are state functions.

  3. Entropy of universe tends to be maximum.
    Exothermic reaction has -ve sign for H

  4. i think increase

  5. Yes the mcq is wrong

  6. 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.

  7. i think increase
