The reaction A(g) + 2B(g) rarr C(g) + D(...

The reaction `A(g) + 2B(g) rarr C(g) + D(g)` is an elementary process. In an experiment involvig this reaction, the initial partial pressure of `A` and `B` are `p_(A) = 0.60 atm` and `p_(B) = 0.80 atm`, respectively. When `p_(C ) = 0.20 atm`, the rate of reaction relative to the initial rate is

A

`1//6`

B

`1//12`

C

`1//36`

D

`1//18`

Text Solution

Verified by Experts

The correct Answer is:
A
`A(g) + 2B(g) rarr C(g)+D(g)`
`{:(t=0,0.6,0.8,-,-),(t=t,0.4,0.4,0.2,0.2):}`
`r_(0) = k xx 0.6 xx (0.8)^(2)`
`r_(1) = k xx 0.4 xx (0.4)^(2)` ltbr. `rArr (r_(1))/(r_(0)) = (0.4 xx (0.4)^(2))/(0.6 xx (0.8)^(2)) = (1)/(6)`
