Some oxidation reactions of methane are given below. Which of them is/are controlled oxidation reactions?

A

`CH_4 (g) +2O_2(g) to CO_2 (g) + 2H_2O (l)`

B

`CH_4(g) + O_2 (g) to C (s) + 2H_2O(l)`

C

`CH_4(g) + O_2(g) overset(Mo_2O_3)to HCHO + H_2O`

D

`2CH_4(g) + O_2 overset"Cu/523 K/100 atm"to 2CH_3OH`

Text Solution

Verified by Experts

The correct Answer is:
C, D
Reaction (c ) and (d) in which `CH_4` does not undergo complete combustion to give `CO_2` and `H_2O` or incomplete combustion to C and `H_2O` are controlled oxidation reactions.
