What are a set of conditions would result in a reaction that is unambiguously non-spontaneous?
endothermic, increasing entropy
Effects of temperature and pressure on exothermic and endothermic reaction?
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
What would you expect from an endothermic reaction?
Endothermic reactions are characterized by the release of heat during the reaction. A typical example is the combustion of methane, which when combined with oxygen releases water and carbon dioxide.
Which piece of evidence would prove that a reaction is exothermic?
All you need is a thermometer. If the temperature rises as the reaction goes to completion, then the reaction is exothermic. If the temperature decreases, then it's endothermic.

endothermic, increasing entropy
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.
How would you know if a reaction was endothermic or exothermic?
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
Which of the following is an example of an exothermic reaction?
does it matter? an exothermic reaction has heat as a biproduct of the product while an endothermic reaction has heat as a part of the reactants. meaning heat is released in exothermic and absorbed in endothermic
Is an exothermic reaction one in which heat is transferred from the surroundings to the reactants?
No. That would be an endothermic reaction.
Explain what it means for a reaction to be endothermic and what would happen to the temperature recorded by a thermometer in an endothermic reaction?
An endothermic reaction absorbs heat energy from the system. In an endothermic reaction a thermometer measuring the reactants and products would register a decrease in temperature.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

Explain which type of reaction exothermic or endothermic would be required to make a cold and a cold pack or hot pack?
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
Exothermic reaction
