The normal force on the book ... the upward force of the table against the
book ... must be exactly equal to the weight of the book, and acting in the
direction exactly opposite to the force of gravity.

If the normal force didn't exactly balance the force of gravity on the book,
so that their sum is zero, then instead of just laying there, the book would
be accelerating.

My best guess would be:

"A force equal in magnitude but opposite in direction"

However I assume that this question is multiple choice, by the way it is introduced. Therefore it would be helpful if these options were also displayed - hence take this as my best guess only.

son4ous [18]

Free energy is a thermodynamic potential that can be used to calculate the maximum reversible work that can be performed by a thermodynamic system at a constant temperature and pressure. It is fulfilled that if the energy change is less than zero it will mean that the relationship will proceed towards the product, while if the relationship is greater than zero the reaction will proceed towards the reactant. Therefore the correct option is D.

<em>The free energy change of a reaction can determine the reaction direction</em>
