One litre co2 is passed through red hot coke. the volume becomes 1.4 litres at the same temperature and pressure. write the composition of the product

Reaction,

CO2 + C → 2CO

Let x lit of CO2 gives 2x lit of CO

Volume left of CO2 = (1-x)

Total volume = 1.4 lit

(1-x) + 2x = 1.4

1+x= 1.4

x= 0.4 lit

As CO = 2x

= 2×0.4

CO = 0.8 lit

Volume of CO2 = 1.4- 0.8

= 0.6 lit
