Ea and rate constant

Postby kshalbi » Sat Mar 12, 2016 12:02 pm

When an enzyme lowers the Ea and causes the reaction to speed up, is it also lowering k or just lowering the activation energy. Or is activation energy calculated into k?

an enzyme only lowers the activation energy. since the activation energy is being lowered, the reaction happens faster therefore k (the rate) would increase

I've been a little confused on what k can be affected by because it is a constant. Is it affected by temperature, concentrations, and catalysts? Or are there more factors besides this?

Increasing the number of catalysts may not increase the rate constant.
