The half-life for a second-order reaction is $30 \ min$. If the initial concentration is $0.1 \ M$,then the value of the rate constant will be $............ \ M^{-1} \ min^{-1}$.

What is the order of reaction if the unit of the rate constant is $s^{-1}$?

$A$ reaction involving different reactants can never be a/an......?

For a reaction $2 \ A + B \rightarrow P$,when the concentration of $B$ alone is doubled,the rate does not change,and when the concentrations of both $A$ and $B$ are doubled,the rate increases by a factor of $4$. The unit of the rate constant is,

The rate of the reaction becomes twice when the concentration of reactant becomes $8$ times,then the order of the reaction is:

By “the overall order of a reaction”,we mean
