Vedclass · Answer

(B) For a zero order reaction,the rate is constant and independent of the concentration of the reactant. Thus,$\frac{dx}{dt} = k$ (constant),which matches graph $(iii)$.Also,the half-life period is given by $t_{1/2} = \frac{a}{2k}$,which shows that $t_{1/2}$ is directly proportional to the initial concentration $a$. This matches graph $(i)$.Graph $(ii)$ represents a second order reaction ($1/x$ vs $t$ is linear for second order).Graph $(iv)$ represents a first order reaction ($\log(a-x)$ vs $t$ is linear for first order).Therefore,graphs $(i)$ and $(iii)$ represent a zero order reaction.

Which of the following graphs represents a zero order reaction?
($a = $ initial concentration of reactant,
$x = $ concentration of reactant consumed,
$t = $ time)
