Temperature and catalyst presence can affect the rate constant, as seen in the Arrhenius Equation

Temperature and activation energy affect the rate constant. When temperature increases, more reactants collide and therefore k increases too. On the other hand, when Ea is high, there is a larger energy barrier and therefore k is smaller.

Catalysts lower the activation energy, meaning particles that are involved in collisions don't need as much energy to make the reaction go forward, increasing k.

The rate constant is affected by the temperature and catalysts in the reaction.

Rate constant is affected by temperature and activation energy in the equation. Catalysts lower the activation energy and speed up the reaction.
