Chemical Kinetics

The given graph is a representation of the kinetics of a reaction. The $y$ and $x$ axes for zero and first order reactions, respectively, are:

Question 85 as printed in the NEET 2022 booklet

A.Zero order ( $y$ = rate and $x$ = concentration), first order ( $y$ = rate and $x$ = $t_{1/2}$ )
B.Zero order ( $y$ = concentration and $x$ = time), first order ( $y$ = $t_{1/2}$ and $x$ = concentration)
C.Zero order ( $y$ = concentration and $x$ = time), first order ( $y$ = rate constant and $x$ = concentration)
D.Zero order ( $y$ = rate and $x$ = concentration), first order ( $y$ = $t_{1/2}$ and $x$ = concentration)✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
