Question #21208

Q. One litre of CO2 is passed over hot coke. The volume becomes 1.4 litre. The composition of product is-

(i) 0.6 ltr CO (ii) 0.8 ltr of CO2 (iii)0.6 ltr of CO2 and 0.8 ltr of CO (iv) None

(i) 0.6 ltr CO (ii) 0.8 ltr of CO2 (iii)0.6 ltr of CO2 and 0.8 ltr of CO (iv) None

Expert's answer

Equation of the reaction:

CO

According to equation, when 1 litre of CO

composed from CO and non-reacted CO

If x litres of CO

V(mixture) = V(new volume CO

V(new volume CO

V(CO) = 2x

So, we have equation:

1.4 = 1 - x + 2x

The solution is x = 0.4 L

Thus, the mixture consist from 1-0.4=0.6 L of CO2 and 2*0.4=0.8 L of CO (iii)

Answer: (iii)

The composition of product is 0.6 ltr of CO2 and 0.8 ltr of CO.

CO

_{2}+ C = 2COAccording to equation, when 1 litre of CO

_{2}reacts with 1 mol of coke, twolitres of CO are formed. Our mixture of gases has volume 1.4 L. Thus it iscomposed from CO and non-reacted CO

_{2}.If x litres of CO

_{2}are reacted, 2x liters of CO are formed. Total volume ofmixture is the sum of CO_{2}and CO volumes:V(mixture) = V(new volume CO

_{2}) + V(CO) = 1.4 LV(new volume CO

_{2}) = V(initial volume CO_{2}) - V(reacted CO_{2}) = (1 - x) LV(CO) = 2x

So, we have equation:

1.4 = 1 - x + 2x

The solution is x = 0.4 L

Thus, the mixture consist from 1-0.4=0.6 L of CO2 and 2*0.4=0.8 L of CO (iii)

Answer: (iii)

The composition of product is 0.6 ltr of CO2 and 0.8 ltr of CO.
