100 ml of gaseous mixture containing `CO, CO_(2) and O_(2)` was sparked there was contraction of 80mL volume when the nixturc was passed through aqueous caustic potash KOH. The omposition of initial gaseous mixture will be respectively:

Answer

c,d

Explanation

`CO+(1)/(2)O_(2) to CO_(2)`
10mL `O_(2)` will give 20mL `CO_(2)` in above reaction. Thus, total volume of `CO_(2)` will be 80mL which will be absorbed in caustic potash KOH. Similarly in (c ) O option, 30mL `CO_(2)` will be formed on sparking.
`underset("Limiting")underset("30mL")(CO)+(1)/(2)O_(2) to underset("30mL")(CO_(2))`
Total volume of `CO_(2)` will be 80mL
