Rate constant k

Postby Stevin1H » Thu Mar 07, 2019 10:10 am

What conditions will affect the value of rate constant k and how does it change the rate constant?

According to my understanding, Factors that affect the rate constant include adding a catalyst/ enzyme which lowers the activation energy of the reaction by allowing it to proceed faster since it will organize the orientation of the particles in a specific manner that is easier for the reaction to proceed. Moreover, Temperature plays a major role because by increasing the temperature allows particles to move faster and thus affect the rate of the reaction.

K is a constant and does not change because k is characteristic for a specific reaction at a specific temperature. It follows that a different reaction, or even that same reaction at a different temperature, would result in a different value for k.

Temoerature and the addition of enzymes would affect the rate constant, as temperature plays a significant role when determining chemical reaction rates.
