A + 2 B to C + D .if - (d [A])/(dt ) = 5 xx 10^(-4) mol l^(-1) s^(-1) , then - (d[B])/(dt) is

Answer»

`2.5 XX 10^(-4)` mol `l^(-1) s^(-1)`
`5.0 xx 10^(-4)` mol `l^(-1) s^(-1)`
`2.5 xx 10^(-3)` mol `l^(-1) s^(-1)`
`1.0xx 10^(-3)` mol `l^(-1) s^(-1)`

Solution :` A + 2 B to C + D`
`(-d[A])/(dt) = 5 xx 10^(-4) implies (-1)/(2) (d[B])/(dt) = 5 xx 10^(-4)`
`(d[B])/(dt) = 10 xx 10^(-4) = 10^(-3)`
