Expert Answer
The reaction equation is as,
 
    CO2    +    C  →   2CO
    1 v            1 v       2v
 
Let x lit of   CO2 gives 2x lit of CO
 
Volume left of CO2 = (1-x)
 
Total volume = 1.4 lit
 
So,
(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
 
Composition of product is 0.8 lit CO and 0.6 lit of CO2.
