For zero order reaction, a plot of $t_{1 / 2}$ versus $[A]_{0}$ will be

A A straight line passing through the origin and slope $= K$
B A horizontal line (parallel to $x$ - axis)
C A straight line with slope $- K$
D A straight line passing through origin and slope $= \frac{1}{2 K}$

Verified Solution

Answer & Solution

Correct Answer

(D) A straight line passing through origin and slope $= \frac{1}{2 K}$

Step-by-step Solution

Detailed explanation

For zero order reaction :- Rate = Kconc.0 [A]0 is the initial concentration and [A]t is the concentration after some time. Over the half life, the concentration also becomes [A]02. So, K=[A]0-[A]02t12=[A]02t12So, t12=[A]02k Graph :- Hence, the straight line passing through…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
