The rate of reaction is expressed as :
`(1)/(2)(+d)/(d t)[C] = (1)/(3)(-d)/(d t)[D] = (1)/(4)(+d)/(d t)[A] = -(d)/(d t)[B]`
The reaction is:

Options

A. `4 A+B rarr 2C + 3D`
B. `B + 3D rarr 4A + 2C`
C. `4 A + 2 B rarr 2C + 3D`
D. `B + (1//2)D rarr 4 A + 3`

Answer

B

Explanation

`-(1)/(3) (d[D])/(d t) = -(d[B])/(d t) = (1)/(2)(d[C ])/(d t) = (1)/(4)(d[D])/(d t)`
`B + 3D rarr 2C + 4A`
`B + 3D rarr 4A + 2C`
