How are endothermic and exothermic reactions the same how are they different?

Endothermic reactions and Exothermic reaction are never the same.

They are both different.

Definitions

Endothermic: - reactions that take in energy. For example: - electrolysis, thermal decomposition and the reaction between ethanic acid and sodium carbonate.

Exothermic: - reactions that transfer energy to the surroundings. For example: - burning, neutralisation and the reaction between water and calcium oxide.
