Is an exergonic reaction always exothermic, or are there exceptions where the two terms do not align?
An exergonic reaction is not always exothermic. While exergonic reactions release energy, they can be either exothermic (release heat) or endothermic (absorb heat). The terms exergonic and exothermic do not always align because exergonic refers to the overall energy change in a reaction, while exothermic specifically refers to the release of heat.
What else can I help you with?
Is an exothermic reaction always spontaneous?
No, an exothermic reaction is not always spontaneous. The spontaneity of a reaction depends on factors such as temperature, pressure, and the entropy change of the system.
For which of reaction listed below will gibbs free energy always be positive?
Guys watch out the question, if your question end with positive then the answer will be An endothermic reaction that decreases in entropy. If the question end with negative then its An exothermic reaction that increases in entropy--APEX hope this help
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
Is an exothermic reaction always spontaneous?
No, an exothermic reaction is not always spontaneous. The spontaneity of a reaction depends on factors such as temperature, pressure, and the entropy change of the system.
Is evaporating always an exothermic reaction?
No, evaporating is not always an exothermic reaction. Evaporation is the process of a liquid turning into a gas, and whether it is exothermic or endothermic depends on the specific conditions such as temperature and pressure.
What is an example of a chemical reaction that releases energy?
One example of a chemical reaction that releases energy is the combustion of methane gas (CH4) in the presence of oxygen. This reaction produces carbon dioxide (CO2) and water (H2O) along with a significant amount of heat and light energy.
An exothermic reaction always?
Releases energy by light or heat
Does an exergonic reaction become hot?
An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic). An exergonic Reaction will give off heat. The higher energy level (Reactants) will produce a lower energy level (products) and release energy (chemical or kinetic).
Is aerobic cellular respiration exergonic?
Yes, cellular respiration is an example of an exergonic reaction (releasing energy for usage) as opposed to photosynthesis (the plant's need the sun's energy to create glucose) an endergonic reaction.Why? Cellular respiration breaks down glucose molecules(which contain energy), so energy is released. The reactants start with a high level of energy(the reactants are whole glucose molecules) and the products are created with a low level of energy because energy is released. The energy that is released from this process can be used to perform work in the cell.No, it releases energy.
Is reactants to products endothermic?
Not always. In a chemical reaction, the process can be either endothermic or exothermic. Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat into the surroundings. The specific reaction will determine whether it is endothermic or exothermic.

The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Energy is always transferred through heat from?
In an exothermic reaction, energy is transferred from the substance reacting to its surroundings. Some common exothermic reactions are burning things, making ice cubes, and mixing water and strong acids.
What is an exothermic reaction?
An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.
Why is combustion exothermic reaction?
because during combustion heat energy is released. for example the burning of carbon in air is a combustion reaction but in this process 393.7 K.J/mol energy is released
