Is spontaneous reaction exo or endo?
Reactions are described by this equation: GD = HD - TDS where D = delta for change in values. GD < 0 spontaneous HD < 0 exothermic ; HD > 0 endothermic The first equation is Gibbs free energy. When G is negative, the reaction is spontaneous. In contrast, a positive number G is non spontaneous. The interesting thing is that spontaneous reactions can be EITHER exothermic and endothermic. Lets look at this: lets assume HD has a value of 100. This means TDS would have to be bigger than 100 in order to make GD a negative number. An endothermic reaction which has a positive H can still be exothermic. Here's another way to pose your question: Is an exothermic reaction spontaneous? Always. Is an endothermic reaction spontaneous? This can be either.
Is the reaction between potassium permanganate and glycerin a endothermic or exothermic reaction?
The reaction between potassium permanganate and glycerin is exothermic, which means it releases heat as it proceeds. This reaction is highly exothermic and can lead to spontaneous combustion in some cases.
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
What kind of enthalpy change favors a spontaneous reaction?
For a spontaneous reaction, the overall change in enthalpy should be negative (exothermic). This means that the products have a lower enthalpy than the reactants, releasing energy in the form of heat.
If rubidium is added to water will it be endothermic or exothermic?
The reaction between rubidium and water is highly exothermic, leading to the spontaneous production of hydrogen gas and the formation of rubidium hydroxide. This exothermic reaction is typically very vigorous and can even result in the ignition of the hydrogen gas produced.
Which reaction released energy?
An exothermic reaction (often a spontaneous one)

Is candle burning a spontaneous or non spontaneous reaction?
Candle burning is a spontaneous reaction. It is an exothermic reaction that occurs naturally and releases heat and light energy as the wax is being oxidized in the presence of oxygen from the air.
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
For which of reaction listed below will gibbs free energy always be positive?

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 kind of enthalpy change favors a spontaneous reaction?
For a spontaneous reaction, the overall change in enthalpy should be negative (exothermic). This means that the products have a lower enthalpy than the reactants, releasing energy in the form of heat.

The synthesis of carbon disulfide is spontaneous and exothermic at room temperature what must be true regarding this reaction?
The reverse reaction is endothermic and nonspontaneous.
Is an endergonic reaction spontaneous or not?
No, an Endergonic Reaction is not spontaneous because it requires a minimal amount of energy to get the reaction to actually start. That amount of energy required to start the reaction is called the Activation Energy.
What happens in a exothermic reaction?
In an exothermic reaction, heat is released to the surroundings. This typically results in an increase in temperature, and the surroundings feel warm. The reactants have higher energy than the products, and the reaction is often spontaneous.
