`2Ararr4B+D` , in this reaction, concentration of B increases to `2xx10^(-3)"mol.L"^(-1)` after 10s from the start of the reaction . Calculate : rate of disappearance of A.

Explanation

`-(1)/(2)(Delta[A])/(Deltat)=(1)/(4)(Delta[B])/(Deltat)`
or, `-(Delta[A])/(Deltat)=(1)/(2)(Delta[B])/(Deltat)=(1)/(2)xx2xx10^(-4) `
`=10^(-4)"mol.L".s^(-1)`
` therefore` Rate of disappearance of A = `10^(-4)mol.L^(-1).s^(-1)`
