# Which of the Following is Not an Endothermic Reaction? (A) Caco3 → Cao + Co2 (B) 2h2o →2h2 + O2 (C) 6co2 + 6h2o → C6h12o6 + 6o2 (D) C6h12o6 + 6o2 → 6co2 + 6h2o - CBSE Class 10 - Science

#### Question

Which of the following is not an endothermic reaction?

(a) CaCO3 → CaO  +  CO2

(b) 2H2O →2H2 + O2

(c) 6CO2 + 6H2O → C6H12O6  +  6O2

(d) C6H12O6  + 6O2 → 6CO2  + 6H2O

#### Solution

(d) C6H12O6 + 6O2 → 6CO2 + 6H2O
This is the reaction of respiration process in which glucose burns in oxygen to produce heat energy needed by our body. So, this reaction is an exothermic reaction.

Is there an error in this question or solution?
