One ltre of CO2 are passed over hot coke.
The volume becomes 1.4litre.
The composition of productis.
1 Answer
Om
When CO2 is passed over coke the folloeing reaction takes place
CO2+C=2CO
So if 1 L of CO2 is completely reacted we should get 2 L of CO but there was only 0.4 L volume increase.
So some volume of CO2 did not participate in reaction
By unitary method we can say that:-
As ther was a 0.4L increase in volume the must be 2*0.4 L = 0.8 L of CO is the final mixture
And the remaining 0.6 L would be the unreacted CO2
So the composition of the reactants is 0.8 L CO and 0.6 L CO2 .
I hope this answer is helpful to you
