Rate constant K = A×exp(-Ea/RT)
It is independent of the order of reaction. It depends only on the temperature of the reaction. So, rate constant would be unaffected even when concentration of reactants change.

no its wrong
actual is(there is no change in rate constant k)
Yes, I got that. Edited
Thanks for the help!
Hi
When temperature increases , rate of reaction increases or decreases?

Final Answer : 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.
Rate constant is independent of concentration of reactant species, so it will be same in changing concentration..
:::::-
For Justification,
By Arrhenius Equation,
Rate Constant expression is given in pic.
Where
T = Temperature at which reaction is carried out.
A = Arrhenius Parameter
Ea = Activation Energy of a reaction.
R = Universal Gas Constant. .
Depends on reaction and Temperature of it.
