Question

The given graph is a representation of kinetics of a reaction.

The $y$ and $x$ axes for zero and first order reactions, respectively are

• 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 $x=$ concenration $)$

Answer 1

Answer: (C)

(I) curve is suitable for zero order if $y=$ rate and $x=$ concentration because in case of zero order reaction rate is constant and does not depend on conc ${}^n$.
(II) curve is suitable for first order if $y=t_{1/2}$ and $x=$ conc ${}^n$ because in case of first order $t_{1/2}$ does not depend on conc ${}^n$.
