Pick out the endothermic reaction out of the following ?
Correct answer: C. CaCO3 = CaO + CO2
- A. C+ ½O2 = CO
- B. CO + 3H2 = CH4 + H2O
- C. CaCO3 = CaO + CO2
- D. CO + ½O2 = CO2
Explanation
The decomposition of calcium carbonate requires heat, so CaCO3 → CaO + CO2 is endothermic. Combustion and partial oxidation reactions listed here release heat.
