Fill up the blank :

$1.$ The rate of zero order reaction depends on ........... concentration of reactant.

$2.$ The molecularity of slow step is equal to ........... of overall reaction

$3.$ Rate  $=$ ........ $[A]^x$ $[B]^y$

From the following which is a second order reaction

Write unit of rate constant of following reaction :

$1.$ fourth order

$2.$ third order

For which order reaction a straight line is obtained along with $x\,-$ axis by plotting a graph between half life $({t_{1/2}})$ and initial concentration $ 'a'$

State a condition under which a bimolecular reaction is kinetically first order reaction.

For a reaction $X + Y \to Z$, rate $ \propto \, [X]$. What is $(i)$ molecularity and $(ii)$ order of reaction ?
