Given below are 4 graphs [A], [B], [C] and [D]

Identify the 2 graphs that represent a Zero order reaction?
- A [C] and [D]
- B [B] and [C]
- C [A] and [B]
- D [A] and [D]
Answer & Solution
Correct Answer
(A) [C] and [D]
Step-by-step Solution
Detailed explanation
For a zero order reaction, the rate law is given by \(\text{Rate} = k[R]^0 = k\). This implies that the rate of the reaction is independent of the concentration of the reactant \([R]\). Thus, a plot of \(\text{Rate}\) versus \([R]\) is a horizontal straight line, which…
