A spontaneous reaction is one that occurs naturally without the need for external energy. Typically, these reactions are characterized by a decrease in free energy, often associated with an increase in entropy (disorder) or the release of heat (exothermic). For example, the combustion of fossil fuels is a spontaneous reaction as it releases energy and increases the entropy of the system. In general, reactions that result in a stable product formation and favorable thermodynamic conditions are more likely to be spontaneous.
Conditions that are most likely to result in a spontaneous chemical reaction or process, based on the Gibbs free energy equation (ΔG = ΔH - TΔS), include when the change in enthalpy (ΔH) is negative (exothermic) and the change in entropy (ΔS) is positive. When ΔG is negative, the reaction will be spontaneous at the given temperature.
The most spontaneous reaction is typically a reaction that releases a large amount of energy in a short period of time, such as explosions or combustion reactions. These reactions occur quickly and without requiring an external force to initiate them.
To determine which process would be most likely spontaneous, we typically consider factors like changes in enthalpy and entropy. A process that results in a decrease in enthalpy (exothermic) and an increase in entropy (disorder) is generally spontaneous. For example, the melting of ice at room temperature is spontaneous because it absorbs heat (endothermic) but results in a significant increase in entropy. Without specific options provided, it's essential to assess these thermodynamic principles to identify spontaneous processes.
Attitudes are most likely to predict spontaneous behavior when there is a close link between the attitude and the behavior, when the attitude is strong and easily accessible, and when there are no other competing influences on the behavior.
To produce a spontaneous reaction in an electrochemical cell, the half-reaction at the anode must involve the oxidation of a species. If the cathode half-reaction is a reduction, such as the reduction of a metal ion to its elemental form, the corresponding anode half-reaction could be the oxidation of that metal to its ion. For example, if the cathode reaction is ( \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} ), the anode reaction could be ( \text{Zn} \rightarrow \text{Zn}^{2+} + 2e^- ), where zinc is oxidized to provide electrons for the reduction at the cathode.

Spontaneous means without planning. A spontaneous visit to the zoo is one you thought of at the last minute out of nowhere. Spontaneous combustion is when something catches fire without apparent reason, just out of nowhere.

A teratogen is an agent or factor that causes malformation of an embryo. It would be likely to result in a spontaneous abortion, another name for a miscarriage or loss of the unborn child.
Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.

The most likely hypothesis for the experiment was that increasing the temperature would speed up the reaction.
