Question

To an eudiometry tube 20 ml of `A_((g))`, 40ml of `B_((g))`, 30ml of `D_((g))` and 60 ml of `C_((g))` is introduced & subjected to sparking to cause following reation with 100% extent. Calculate the volume change involved due to sparking.
`2A_((g)) + 4B_((g)) to 3P_((g)) + Q_((l))`
`3C_((g)) + D_((g)) to 2P_((g)) + 4R_((g))`
A. 10 m l expansion
B. no volume change
C. 30 ml contraction
D. 50 ml expansion
