no, rate constant does not depend upon concentrations of reactants,

from arhenious equation,  k = Ae^(-Ea/RT)

we can say, that it is dependent on activation energy(Ea) and temperature, and also the presence of a catalyst, as it alters the effective activation energy.

Please approve if you liked.

rate constant DOES DEPEND UPON CONCENTRATION

its only independent in case of a first order reaction

but in other case like zero order or second order

half life depends inversely propotional to a^n-1

where n is order of reaction
