The rate constant of a first-order reaction is 3 xx 10^(-6) per second. If the initial concentration is 0.10 m, the initial rate of reaction is

Answer»

`3 XX 10^(-5) ms^(-1)`
`3 xx 10^(-6) ms^(-1)`
`3 xx 10`
`3 xx 10^(-7) ms^(-1)`

Solution :Given: Rate constant of the first-order reaction `(K) = 3 xx 10^(-6)` per sec and INITIAL concentration `[A] = 0.10 M`. We know that initial rate constant `K[A]=3 xx 10^(-6) xx 0.10 = 3 xx 10^(-7) ms^(-1)`
