Q. Which one is not correct?
A) Rate of zero order reaction depends upon initial concentration of reactant
B) Rate of zero order reaction does not depend upon initial concentration of reactant
C) $t_{1/2}$ of first order reaction is independent of initial concentration of reaction
D) $t_{1/2}$ of zero order reaction is dependent of initial concentration of reaction
Explanation
(a)
The rate of zero order reaction is independent of the concentration of the reactants or the concentration of the reactant do not change with time. Thus, the rate of reaction remains constant.
$\frac{dx}{dt} = k(a - x)^{0} \Rightarrow \frac{dx}{dt} = k$
Or Rate=k
