Chemical Kinetics

The plot of $[A]$ versus time " $t$ " for a zero order reaction is a horizontal line parallel to the $x$-axis which represents " $t$ "

For a first order reaction the time taken for $3 / 4^{\text {th }}$ completion is 2 times the half-life period.

For a second order reaction the rate of reaction with respect to reactant becomes 27 times when its concentration is tripled.

Molecularity of a chemical reaction is always greater than order of the reaction.
