Question
Which of the following is an example of an endothermic reaction?A. Combustion of propane (C33H88) to produce carbon dioxide (CO22) and water (H22O).B. Burning of methane (CH44) in the presence of oxygenC. Formation of table salt (NaCl) from sodium (Na) and chlorine (Cl22).D. Decomposition of hydrogen peroxide (H22O22) into water (H22O) and oxygen (O22).
Solution
The example of an endothermic reaction from the options provided is D. Decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2).
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. In the decomposition of hydrogen peroxide, energy is required to break the bonds in the H2O2 molecule, making it an endothermic reaction.
