Which of the following is an example of an endothermic reaction?
Combustion of propane (C3H8) to produce carbon dioxide (CO2) and water (H2O).
Burning of methane (CH4) in the presence of oxygen
Formation of table salt (NaCl) from sodium (Na) and chlorine (Cl2).
Decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2).
Correct answer is D
The decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2) 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.
