Question

A solution with initial concentration of a mol dm^-3 follow zero order kinetic. The time taken for the completion of reaction is

Options

• `k/a`

• `a/(2k)`

• `a/k`

• `ka`

Answer 1

`a/k`

Explanation:

For zero order reaction = `1/+ {[A] - [A]}`

When the reaction is complete, [A] = 0

K = `[A]^0/t = a/t` or t = `a/k`
