Answer:
The answer to your question is: False, it is an exothermic reaction.
Explanation:
Endothermic reactions needs energy (heat) to happen. Heat is added to the reactants.
Exothermic reactions releases heat, heat is represented in the products.
2C2H2 + 5O2 → 4CO2 + 2H2O + 310 kcal
In this reaction, we notice that 310 kcal is positive and is in the products so this reaction is exothermic.
