Temperature vs. activation energy

Postby Shanzey » Sat Mar 14, 2020 9:11 pm

How does temperature affect rate constant k? Does an increase in temperature cause an increase in the rate constant?

Yes. If you increase T = more collisions = increased rxn rate (knowing rate = k[A]) = increased k

I do believe increasing T also increases k reaction constant.

Just because we are increasing the number of collisions, how does this correlate to a decrease in activation energy? I thought that is something a catalyst does.

More T, more activation energy because more collisions.

As the temperature increases, the amount of energy in the system increases. This energy is then used to overcome the activation energy
