List I and List II contains four entries each. Entries of Column I are to be matched some entries of List II. One or more than one entries of List I may match with the same entry of List II.

Answer 1

$C(s,graphite)+O_2\left(g\right)⟶{CO}_2\left(g\right)$ is a combustion reaction of carbon, also its a formation reaction of $C{O}_2$.

$C(s,graphite)⟶C\left(g\right)$ is a atomization reaction; also its a formation reaction and sublimation.

$CO\left(g\right)+\frac{1}{2}{O}_2\left(g\right)⟶{CO}_2\left(g\right)$ is a combustion reaction of C.

$C{H}_4⟶C\left(g\right)+4H\left(g\right)$ is a atomization reaction.
