how do we know if a reaction is endothermic?!
The temp would fall, this is because it takes more energy/heat to break the bonds between the atoms, if it was exothermic, then more energy would be used to form new bonds, and the temp. raises
correct me if im wrong but i thought it was the other way round
cuz endo takes in heat so temp rises(positive)
and exo gives out heat go temp falls(negative)
the heat source always has a higher temperature than the surrounding
in a redox reaction heat is not displaced it is either produced or used up
here the temperature is referred to the surrounding not the reagents
so in an exothermic reaction heat is produced which increasaes the temp. of the surrounding so the temperature is increased
