6. Which statement about thermodynamics is true?a. Free energy is used up in an exergonic reaction.b. Free energy cannot be used to do work.c. The total amount of energy can change after a chemical transformation.d. Free energy can be kinetic but not potential energy.e. Entropy has a tendency to increase.

Which of the following statements is consistent with the second law of thermodynamics?Question 10Select one:a.A gain of free energy in a system is never associated with conversion of energy from one form to another.b.Without an input of energy, the entropy of an organism would tend to decrease over time.c.Every energy transformation performed by an organism decreases the entropy of the universe.d.A constant input of energy is required to maintain the high level of organisation associated with living cells.

Directions: Select the choice that best fits each statement. The following question(s) refer to the following concepts related to energy(A) Heat flow(B) Kinetic energy(C) Potential energy(D) First law of thermodynamics(E) Second law of thermodynamicsQuestionAn energy transformation occurs and results in increased disorder.

Free energy change is the most suitable criteria for judging the spontaneity of reactions. Derive the equation for free energy change and justify the statement by providing suitable examples.

Which of the following statements best describes a system at chemical equilibrium?Question 11Select one:a.The system can do no work.b.The system releases energy at a steady rate.c.The kinetic energy of the system is zero.d.The system consumes energy at a steady rate.

The second law of thermodynamics states thatMultiple Choicewhenever energy is used, some becomes converted to a form difficult to use to do work.energy cannot be shifted from one form to another.life forms cannot survive without energy.energy exists in both potential and kinetic form.
