In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
Now, since the rate constant increases, this implies that the rate of reaction increases with temperature. Regarding concentration: you are correct in that concentration affects the rate of reaction. However, a rate constant does not change according to concentration.
