The initial rate , `-(d [A])/(dt)` at t = 0 was found to be `2 . 6 xx 10^(-2)` mol `L^(-1) s^(-1)` for the reaction `A + 2B to ` Products The initial rate , `- (d[B])/(dt)` at t = 0 isA. `0.01` mol `L^(-1) s^(-1)`B. `2.6 xx 10^(-2)` mol `L^(-1) s^(-1)`C. `5.2 xx 10^(-2)` mol `L^(-1) s^(-1)`D. `6.5 xx 10^(-3)` mol `L^(-1) s^(-1)`

Answer» Correct Answer - c
`A + 2 B implies ` products
`-(d[A])/(dt) = (-d[B])/(2dt)`
`2.6 xx 10^(-2)` mol `L^(-1) s^(-1) = (-d[B])/(2dt)`
`(-d[B])/(dt) = 2 xx 2.6 xx 10^(-2)`
`= 5.2 xx 10^(-2)` mol `L^(-1) s^(-1)`
