The given graph is a representation of kinetics of a reaction

The \mathrm{y} and \mathrm{x} axes for zero and first order reactions, respectively are

Option: 1

zero order (y= concentration and x= time), first order (y= rate constant and x= concentration)
 


Option: 2

zero order (y=rate and x=concentration), first order (\mathrm{y}={t_{1/2}} and x= concenration)
 


Option: 3

zero order (y= rate and x=concentration), first order (y= rate and \mathrm{x=t_{1/2}})
 


Option: 4

zero order (y= concentration and x=time),first order (\mathrm{ y=t_{1/2,}} and x= concentration)

As we have learnt,

For a zero order reaction,

\mathrm{\text { rate } \alpha[A]^{0}}

\Rightarrow rate = K = constant.

\Rightarrow rate is independent of concentration

For a first order reaction

\mathrm{t_{1 / 2}=\frac{\ln 2}{K} .}

\Rightarrow Half life is independent of concentration

Hence correct option is 2
