- Spontaneity requires $\Delta G
For a certain reaction, $\Delta G^0 = -45$ kJ/mol and $\Delta H^0 = -90$ kJ/mol at 0 °C. What is the minimum temperature at which the reaction will become spontaneous, assuming that $\Delta H^0$ and $\Delta S^0$ are independent of temperature?

- Mg (s) + O₂ (g) → MgO (s) + energy, this reaction may be classified as a/an
- Combination Reaction Two or more reactants (Mg and O₂) combine to form a single product (MgO). This fits the definition of a combination reaction. 2. Oxidation Reaction Magnesium (Mg) reacts with Oxygen (O₂). In this reaction, Mg loses electrons (its oxidation state changes from 0 to +2) and is oxidized. The reaction with oxygen is a classic example involving oxidation. 3. Exothermic Reaction The term "+ energy" on the product side indicates that energy is released during the reaction. Reactions that release energy are classified as exothermic reactions.Since the reaction fits the description of a Combination reaction, an Oxidation reaction, and an Exothermic reaction, all the individual classifications listed are correct. 189. Which of the following are exothermic processes ?
