For, zero order reaction t1 / 2=(a/2 K) and for zero order reaction, concentration is independent from sate. So, (d x/d t) is constant. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/046d79fc421f68f72b6727f3ffd93afb-.png" />

Q. Which of the following graphs represents a zero order reaction?
(a = initial concentration of reactant, $x =$ concentration of reactant consumed, $t =$ time)

i, iii, iv

i, iii

ii, iii, iv

i, iv

For, zero order reaction

$t_{1/2} = \frac{a}{2 K}$ and for zero order reaction, concentration is independent from sate.

So, $\frac{d x}{d t}$ is constant.
