Which of the following reactions taking place in the blast furnace during extraction of iron is endothermie ?

A

`CaCO_(3) to CaO+CO_(2)`

B

`2C+O_(2)to2CO`

C

`C+O_(2)toCO_(2)`

D

`Fe_(2)O_(3)+3CO to 2Fe+3CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
When `CaCO_(3)` decomposes to CaO and `CO_(2)`, and heat is absorbed hence reaction is endothermic
`CaCO_(3) overset(Delta)toCaO+CO_(2)`
