Question

Oxidation of Coal results-
Carbon-dioxide
Sulphur-dioxide
Nitrogen-dioxide
Argon​

Answer 1

Answer:

Oxidation results in heating and self-combustion of coal on open storage. For each coal, there is a critical temperature (~60°C) beyond which the heating rate sharply rises and self-ignition becomes possible.

Hope this will help you

Answer 2

Answer:

Oxidation results in heating and self-combustion of coal on open storage. For each coal, there is a critical temperature (~60°C) beyond which the heating rate sharply rises and self-ignition becomes possible. The activation energy of coal oxidation in the range 0–140°C is found to be 13.4–53.6 kJ/mol
