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 toProducts The initial rate , - (d[B])/(dt) at t= 0 is

Answer»

`0.01` MOL `L^(-1) s^(-1)`
`2.6 xx 10^(-2)` mol `L^(-1) s^(-1)`
`5.2 xx 10^(-2)` mol `L^(-1) s^(-1)`
`6.5 xx 10^(-3)` mol `L^(-1) s^(-1)`

Solution :`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)`
