Question
Chapter 6, Problem 6.131QP
Interpretation Introduction
Interpretation:
Qualitative explanation has to be given why decomposition reactions are endothermic, combination reactions are exothermic.
Concept Introduction:
Heat is flow of thermal energy involving two bodies at various temperatures.
The flow of thermal energy involving two bodies at various temperatures is called as heat. The flow of heat implies that energy is either released or absorbed on describing about energy changes that takes place during a process.
Exothermic process is the chemical process in which heat is released to the surroundings.
Endothermic process is the chemical process in which heat is absorbed from the surroundings.
