Fill in the blanks:
$1.$ The rate of a zero order reaction depends on the ........... concentration of the reactant.
$2.$ The molecularity of the slow step is equal to the ........... of the overall reaction.
$3.$ Rate $=$ ........ $[A]^x [B]^y$
$1.$ The rate of a zero order reaction depends on the ........... concentration of the reactant.
$2.$ The molecularity of the slow step is equal to the ........... of the overall reaction.
$3.$ Rate $=$ ........ $[A]^x [B]^y$
(A) $1.$ The rate of a zero order reaction is independent of the concentration of the reactant,meaning it depends on the $0^{th}$ power of the concentration.
$2.$ The molecularity of the slow step (rate-determining step) is equal to the order of the overall reaction.
$3.$ The rate law expression is given by $\text{Rate} = k[A]^x [B]^y$,where $k$ is the rate constant.
$2.$ The molecularity of the slow step (rate-determining step) is equal to the order of the overall reaction.
$3.$ The rate law expression is given by $\text{Rate} = k[A]^x [B]^y$,where $k$ is the rate constant.
