Question

Integrated rate law equation for a zero order reaction is ______.

Options

• K_t = [A]₀ − [A]_t

• `K_t = 2.303 log_10  [A]_0/[A]_t`

• `K = ([A]_t - [A]_0)/t`

• `K_t = 2.303 log_10  ([A]_t)/[A]_0`

Answer 1

Integrated rate law equation for a zero order reaction is K_t = [A]₀ − [A]_t.

Explanation:

That means:

Rate = `-(d[A])/(dt)` = k

We integrate both sides:

`int_([A]_0)^[[A]) d[A] = -int_0^t  kdt`

[A]_t − [A]₀ ​= −kt

K_t = [A]₀ − [A]_t
