Question

When 500ml 0f co2 gas is passed through red hot charcoal the volume becomes 700 ml . The volume of co2 converted into co is

Answer 1

When 500\ ml\ CO_{2}500 ml CO

2

gas is passed through red hot charcoal the volume becomes 700\ ml700 ml. The volume of CO_{2}CO

2

converted into COCO is

Answer

CO_{2}+C\rightarrow 2COCO

2

+C→2CO

0.5\ L0.5 L 0.5\ L0.5 L 1\ L1 L

Let xx litre CO_{2}CO

2

gives 2x2x litre of COCO

Volume of CO_{2}CO

2

left =(0.5-x)=(0.5−x)

Total volume =0.5-x+2x=0.7=0.5−x+2x=0.7

x=0.2\ litrex=0.2 litre

\therefore∴ Volume of CO_{2}CO

2

converted into CO=200\ mlCO=200 ml

Answer 2

Answer:

200ml LR

Explanation:Co_2 + C =2Co

0.5 L xL 2xL

0.5L-x 0. 2x

C is lr (limiting reagent) as it is a solid and its vol will be neglible as compared to gases.

C will become 0.

So, 0.5L - x + 2x = 0.7L

x = 0.2 L = 200ml Ans.

Thank you and have a nice day.
