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.

What is the mechanism for the formation of endo products in a Diels-Alder reaction?
In a Diels-Alder reaction, endo products are formed when the diene and dienophile approach each other in a way that allows the newly forming bonds to be oriented towards the larger substituents on the dienophile. This results in the more stable endo product being favored over the exo product.
Is the reaction exergonic and spontaneous or not?
Yes, the reaction is exergonic and spontaneous.
A reaction that occurs without provocation from an outside system is?
A spontaneous reaction.
Is the reaction spontaneous or non-spontaneous when considering the keyword "spontaneous vs non-spontaneous"?
In the context of "spontaneous vs non-spontaneous," a reaction is considered spontaneous if it occurs on its own without needing external influence. On the other hand, a non-spontaneous reaction requires external energy input to occur.
What is the reverse of a spontaneous reaction, and how does it differ from a nonspontaneous reaction?
The reverse of a spontaneous reaction is a nonspontaneous reaction. In a spontaneous reaction, the reaction occurs naturally without any external influence, while in a nonspontaneous reaction, external energy input is required for the reaction to occur.
What is the opposite of exo?
The opposite of exo- is endo-.
Aqua regia is the reaction endo or exo?
The reaction of aqua regia is exothermic because it releases heat when the acids interact with metals, causing a very strong and aggressive reaction that can dissolve gold and platinum.
are ants endo or exo?
if u mean skeleton then exo
Does a cockroach have endo skeleton?
No! It has an exo skeleton
Does a blue jay have a endo or exo skeleton?
Endoskeleton
What is the opposite of endo?
Exo- is the prefix opposite to endo-, as in exoskeleton and endoskeleton.
What is the mechanism for the formation of endo products in a Diels-Alder reaction?
In a Diels-Alder reaction, endo products are formed when the diene and dienophile approach each other in a way that allows the newly forming bonds to be oriented towards the larger substituents on the dienophile. This results in the more stable endo product being favored over the exo product.
Are sponges endo or exo?
They're invertebrates. They have no skeletal structure at all
Give the examples for endo and exo skeletons?
Humans and fish have endo skeletons and grasshoppers have exoskeletons (thats why you hear a crack if they are stepped on).
What are the two tissue in body?
There's 3 : inner, outer, & middle. (endo - exo - meso)
What happens during endocytosis and exocytosis how are they different?
substances move. endo folds in , and exo exits
Does a sea horse have a endo skeleton exo skeleton or a hydrostatic skeleton?
It is endoskeleton. Seahorses have an interior skeleton.
