At what temperature does the CO is converted to CO2 in orsat apparatus for analysis of flue gas? Correct Answer 280-295 0C

At the temperature range of 280-295 0C, the CO is converted into CO2. Also the hydrogen present is oxidised to water. The diminution in the volume of gas sample indicates the volume of hydrogen.
