drag and drop each characteristic to show whether it best describes a nonspontaneous or a spontaneous reaction. each option
will only be used once.
nonspontaneous reaction
spontaneous reaction
occurs without an input of energy
free energy lower in products than in reactants
free energy higher in products than in reactants
occurs only if energy is added to the system
more likely to involve an increase in entropy

Explanation:

• A spontaneous reaction occurs without an input of energy. In such reactions, the free energy of the products is lower than that of the reactants ($\Delta G=\text{G}_{\text{products}}-\text{G}_{\text{reactants}}<0$), and they are more likely to involve an increase in entropy (as per the second law of thermodynamics, which states that the entropy of the universe tends to increase).
• A non - spontaneous reaction occurs only if energy is added to the system. Here, the free energy of the products is higher than that of the reactants ($\Delta G=\text{G}_{\text{products}}-\text{G}_{\text{reactants}}>0$).

Answer:

• Nonspontaneous reaction: Free energy higher in products than in reactants, Occurs only if energy is added to the system
• Spontaneous reaction: Free energy lower in products than in reactants, Occurs without an input of energy, More likely to involve an increase in entropy
