One litre of CO2 is passed over hot coke. The volume becomes 1.4 lit. The resultant mixture contains

a
0.6 lit CO2
b
0.6 lit CO
c
0.8 lit CO
d
0.8 7lit CO2

detailed solution

Correct option is A

C(s)+CO2(g)2CO(g)

1mol         2mol            

(1 − x)         2x

Total volume (1 − x) + 2x = 1 + x= 1.4

x=0.4 Lt

Given volume of CO2=1 Lt

Volume of CO2 remain = 1 − 0.4 = 0.6 Lt

Volume CO formed = 2 × 0.4 = 0.8 Lt .
