Respuesta :
The curve of the reaction pathway graph goes up that means heat is being absorbed.
What is heat?
As molecules in a substance increase in velocity when collision increases in frequency as well as intensity, heat is generated in terms of light radiation. Each collision causes energy to be released. Chemical reactions produce heat as a byproduct.
What is reaction pathway graph?
Reaction pathway graph tells about the energy changes that occur through chemical reactions. It is easy to understand that the reaction is exothermic or endothermic.
When the curve of a reaction pathway graph rises, it indicates that heat will be absorbed; when it falls, it indicates that heat would be released during a chemical reaction.
