Explanation:

Red hot coke reduces CO

2

to CO. The balanced equation is CO

2

+C→2CO.

∴1 mol of CO

2

will give 2 mol of CO.

x L of CO

2

will give 2x L of CO.

In the question, 1 L of CO

2

will react to give 1.4 L of mixture.

Out of 1 L, x L of CO

2

reacts. The unreacted quantity is 1−x.

Total volume of mixture = unreacted CO

2

+ volume of CO formed.

Total volume of mixture =1−x+2x=1.4 L.

Hence, x=0.4 L.

Thus, volume of CO formed = 2×0.4 L =0.8 L.

Volume of CO

2

left = (1−0.4)L=0.6 L.
