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.
Does the entropy of the surroundings increase for spontaneous processes?
Yes, the entropy of the surroundings increases for spontaneous processes.
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.
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 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.
Does the entropy of the surroundings increase for spontaneous processes?
Yes, the entropy of the surroundings increases for spontaneous processes.
Is spanish moss endothermic or exothermic?
Exothermic. All living things are exothermic due to processes of metabolism.
Why is the diffusion of a gas in a vacuum exothermic?
It is exothermic because the gas is expanding. Most processes that have to do with expansion are exothermic/
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
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.
Why are all spontaneous processes irreversible?
Spontaneous processes are irreversible because they involve an increase in entropy, or disorder, in the system. This increase in entropy leads to a loss of energy that cannot be fully recovered, making the process irreversible.

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.
What is the difference between non spontaneously and spontaneously?
Non-spontaneous processes require intervention or energy input to occur, while spontaneous processes occur on their own without needing external help. Spontaneous processes tend to move towards equilibrium, while non-spontaneous processes move away from equilibrium.
Which o the following would most likely be spontaneous?
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.
