Answer: Free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
Explanation:
It is known that free energy change is represented by the symbol . Free-energy helps in determining the direction of a chemical reaction like if it is taking place in forward or backward reaction.
For a spontaneous reaction, the standard free-energy change is negative in nature and the reaction will proceed in forward direction.
Thus, we can conclude that free-energy change of a reaction is a measure of the direction in which a net reaction occurs.

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Written Answer: Covalent bonds hold atoms together in molecules and polyatomic ions where as intermolecular forces hold molecules together in a liquid or solid. Intermolecular forces are generally much weaker than covalent bonds.
Explanation/Evidence: "In contrast to intramolecular forces, such as the <u>covalent bonds that hold atoms together in molecules and polyatomic ions</u>, <u>intermolecular forces hold molecules together in a liquid or solid.</u> <u>Intermolecular forces are generally much weaker than covalent bonds."</u>
