When do you leave the equilibrium constants and when do you substitute k/k'? For example, in the one Dr. Lavelle did in lecture, he got rate=2k2*K*[NO]^2*[O2]. He then replaced K with k1/k1' to get rate=2k2*k1/k1'*[NO]^2*[O2]. Do you always replace K or are there times where you have to leave it in?
replacing K helps with understanding the rate of the reactions. When writing the rate law, you use rate constants and not K as K just means the reaction is at equilibrium, Having k/k' is more representative of rates in relation to concentration
