Which of the following is an example of an endothermic reaction?
Combustion of propane (C\(_3\)H\(_8\)) to produce carbon dioxide (CO\(_2\)) and water (H\(_2\)O).
Burning of methane (CH\(_4\)) in the presence of oxygen
Formation of table salt (NaCl) from sodium (Na) and chlorine (Cl\(_2\)).
Decomposition of hydrogen peroxide (H\(_2\)O\(_2\)) into water (H\(_2\)O) and oxygen (O\(_2\)).
Correct answer is D
The decomposition of hydrogen peroxide (H\(_2\)O\(_2\)) into water (H\(_2\)O) and oxygen (O\(_2\)) is an endothermic reaction because it requires energy to break the bonds in the hydrogen peroxide molecule. The process absorbs heat from the surroundings to drive the reaction.
