One litre of `CO_(2)` is passed over hot coke. The volume becomes `1.4 L`. Find the composition of products, assuming measurement at `NTP`.

Text Solution

Verified by Experts

`CO_(2) + C rarr 2CO`
`"Initial" 1 L a`
`"Final" (1 - a) L 2a`
The volume `= (1 - a + 2a) = 1 + a`
`:. 1 + a = 1.4`
`a = 0.4 L`
Volume of `CO_(2)` left `= 1 - 0.4 = 0.6 L`
Volume of `CO` formed `= 2 xx 0.4 = 0.8 L`
