If concentration time graph of a reactant indicate a constant half life, then the order of reaction with respect to reactant is MDCAT2018

When initial concentration of a reactant is doubled in a reaction its half life period is not effected NEET2015-cancelled

If the rate constant for a first order reaction is k, the time required for completion of 99% of the reaction is given by  [NEET2019]

The rate constant for First order reaction is 4.6x10^-3s^-1 . the time required to reduce 2.0g of the reactant to 0.2g is:::: [NEET2020]
