### Re: rate constant

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

### Re: rate constant

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.

### Re: rate constant

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.

### Re: rate constant

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

### Re: rate constant

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