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.
Endothermic produces a cold reaction and exothermic produces a hot reaction.

The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
If the test tube containing the reactants mixture became hotter then it is exothermic, and if it became colder then it is endothermic. You must do the reaction to know which is which!
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
I don't know for sure, but it is probably exothermic. (PLEASE CORRECT ME!)
No.I know that in endothermic reactions things absorb heat or get colder. In exothermic reactions they release heat or get warmer. So, since the container gets hot I guess the energy is exothermic.
Exothermic phenomenon: with generation of heat Endothermic phenomenon: with absorption of heat
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
i dony know

When a reaction has products that have a lower temperature than the reactants did, the reaction is endothermic.

If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.

A chemical reaction that releases energy is called an exothermic reaction.

The temperature will decrease.
