Question

one litre CO2 is passed through red hot coke. the volume becomes 1.4L at STP. What is the composition of the products.(pls explain this in a simple way)

Answer 1

volume of CO2 is 1L
total product formed after CO2 reacts with Coke=1.4L
CO2+C=2CO
1:1:2
1L of CO2 will produce =2L of CO
1/2L of CO2 = 1L of CO
1.4/2L of CO2 =1.4L of CO
0.7L of CO2=1.4L of CO
unused CO2=1-0.7=0.3L
Therefore total product formed= 1.4L of CO+0.3L of CO2
