(In some cases … WebMar 8, 2024 · Why does temperature affect the rate constant? Increasing the temperature of a reaction generally speeds up the process (increases the rate) because the rate constant increases according to the Arrhenius Equation. As T increases, the value of the exponential part of the equation becomes less negative thus increasing the value of k.
