In the reaction,`A+2Brarr3C+4D,` the rate of disappearance of B at a given time is `10^(-2)"mol. "L^(-1).s^(-1)` Calculate
the rate of reaction

Explanation

For this reaction,
`-(d[A])/(dt)=-(1)/(2)(d[B])/(dt)=(1)/(3)(d[C])/(dt)=(1)/(4)(d[D])/(dt)`
`therefore "rate of reaction" = (1)/(2)xx(-(d[B])/(dt))=(1)/(2)xx10^(-2)`
`[because - (d[B])/(dt)=10^(-2)"mol . L"^(-1) .s^(-1)]`
`= 5xx10^(-3)"mol"^(-1).s^(-1)`
