What should be the free energy so that reaction is spontaneous?(a) Positive(b) Negative(c) Neutral(d) None of the mentionedI have been asked this question in quiz.I'd like to ask this question from Thermodynamics and Kinetics topic in portion Hydrolysis of Unit Processes

Answer»

The correct choice is (B) Negative

To elaborate: If the free energy change is negative the reaction is spontaneous and BECOMES more favourable with INCREASING (-dF); on the other HAND if the free energy change is positive and greater than 10 kg-cal per mole the reaction is not SUITABLE for practical application.
