Not Change.
Rate Constant will remain same or constant. Understanding : 1) Rate constant for a particular Reaction depends only Temperature of Reaction. 2) Since, we are changing only concentration of reactant species.
According to Arrhenius equation-
Rate constant (K)=Ae^Ea/RT
whereas,
T= Temperature at which reaction is carried out.
A= Arrhenius Parameter
E a= Activation Energy of a reaction.
R= Universal Gas Constant. .
For a particular reaction, rate constant depends on the temperature only and thus is independent of concentration of reactant.
Hence there will be no change in the value of rate constant w.r.t. the concentration of reactant.
