Question

adding a catalyst increases the rate of reaction. If the rate increases, then either k increases, or the order of the reaction changes. Explain which specific trials you might repeat with the catalyst in order to determine which is occurring.

Answer 1

The consistent trial is to vary rate constant with rate of reaction, since as the the rate of reaction increases, the rate constant also increases/decreases depending on which order of reaction is taken into consideration,

Step-by-step explanation:

From the Arrhenius equation

k= Ae^(-Ea/RT) , generally as catalyst is added, the activation energy(Ea) decreases and since rate constant depends essentially on temperature and Rate of reaction on both temperature and concentration
