Question

A reaction is said to be of zero if the rate is entirely independent of the concentration of the reactants.
If true enter 1, if false enter 0.

Answer 1

A reaction is said to be of zero if the rate is entirely independent of the concentration of the reactants.
Thus the reaction having the rate law expression $rate=k[A{]}^0$ is a zero order reaction as the rate of the reaction is independent of the concentration of A.The photochemical reaction for the formation of HCl is a zero order reaction.
$H_2\left(g\right)+C{l}_2\left(g\right)\stackrel{sunlight}{\to }2HCl\left(g\right)$
