When a chemical reaction has a negative delta G is the reaction exothermic or endothermic?

When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative.
Hope this helps :)

What is a chemical reaction that absorbs heat?
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
What is the diffrencence between exothermic reaction and chemical reaction?
Exothermic reaction is just one of the two possible chemical reactions: either exothermic or endothermic. (No difference but heat release)
Is decomposition of phosphorus pentachloride endothermic or exothermic?
Exothermic reaction.
Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
H2O + Na2SO4 = Exothermic reaction
Is the reaction between sodium and water endothermic?
it is exothermic because heat is liberated to the surrounding during the chemical reation
Are titrations endothermic or exothermic?
In thermometric titration the reaction enthalpy is used to follow the chemical reaction. I guess it dépends on the titration reaction it can be exothermic or endothermic. ΔHr (molar heat of reaction) negative (indicating an exothermic reaction) or positive (indicating an endothermic reaction
A chemical reaction that releases energy is called?
Exothermic reactions
A reaction that gives out energy?
... is an exothermic reaction (opposite of 'endothermic')
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
What is a chemical reaction that absorbs heat?
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
Is the chemical reaction in flameless ration heaters classified as an endothermic or an exothermic reaction?
Exothermic. Its a heater.
Is the reaction inside a chemical heat pack endothermic?
The reaction is exothermic.
Is the reaction of magnesium sulfate and water exothermic or endothermic?
It is not a chemical reaction, it is dissolution; this physical process is exothermic.
What is the name given to reactions which take in heat?
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.
Which contains more chemical energy endothermic or exothermic?
An endothermic reaction contains more chemical energy.
What is the difference between an exothermic and an endothermic chemical reaction?
Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
What is the diffrencence between exothermic reaction and chemical reaction?
Exothermic reaction is just one of the two possible chemical reactions: either exothermic or endothermic. (No difference but heat release)
