(i) 15cc (ii) 10cc (iii)32cc (iv)None

Answer 1

Answer on Question #21206, Chemistry / Physical Chemistry

Conditions: 26cc of CO2 are passed over red hot coke. The volume of CO evolved is-

(i) 15cc (ii) 10cc (iii) 32cc (iv) None

Solution:

The reaction is presented below:

$$\mathrm{CO_2} \quad + \quad \mathrm{C} \quad \rightarrow \quad 2\mathrm{CO}$$

V=26cc Xcc

Vm=22.4L 2*22.4L

Here of

26cc/22.4L = Xcc / (2*22.4L)

X=26cc * 22.4L * 2 / 22.4L = 52(cc)

Answer: (iv) None
