Re: k' vs kr
K' represents the placeholder K that is used in psuedo order reactions when the rate law is simplified to only include one species at reaction. For example, if the rate law of a reaction was k[A][B][C] and we wanted to isolate the changes affecting species A, then we could shorten and truncate the rate law into k'[A] where k' is equal to k[B][C]. This is so that it simplifies the equation and turns it into a psuedo first order rate law.

Re: k' vs kr
k' is the rate of the reverse reaction. kr is the rate constant of a reaction that depicts the rate of a chemical reaction.

Re: k' vs kr
kr is the rate constant of the reaction, while k' is the rate of the reverse reaction, their relation can be shown as kr/k'=K

Re: k' vs kr
K' is the rate constant for the reverse reaction which is why k/k' is the equilibrium constant K
Re: k' vs kr
Is k’ and k prime have to be positive right? Like just because k’ is the reverse reaction doesn’t mean it has a negative sign

Yes, it always has to be positive because the Arrhenius Equation is always positive.
