A gaseous `A_(2)(g) rarr B(g) +(1)/(2) C(g)`, shows increase in pressure from 100 mm to 120 mm in 5 min. The rate of disappearance of `A_(2)` is

A

`4 mm, min^(-1)`

B

`40 mm, min^(-1)`

C

`8 mm, min^(-1)`

D

`20 mm min^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`A_(2) to B + 1/2 C`,
`100 + x/2 = 120`
x= 40
Rate `=(dx)/(dt) = 40/5 = 8 mm.min^(-1)`
