How does temperature affect rate of reaction

WebRaising the reaction temperature by 10 °C can double or triple the reaction rate. This is due to an increase in the number of particles that have the minimum energy required. The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Webthe rate of a reaction depends on the rate constant and concentration R=k[A][B].. the rate constant according to Arrhenius is as u stated. from ur equation u can see that concentration doesnt affect k but affects R. Temperature affects k and k affects R so, temperature affects both while concentration affects only Rate of reactions.
