k' vs kr

[Jorja De Jesus 2C]

What is the difference between k' and ?

[Nawal Dandachi 1G]

K' is reverse reaction

[Kevin Xu 4F]

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.

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

K’ is the rate of the reverse reaction. kr is the rate constant of the reaction

[Hannah Romeo 1J]

K’ is the rate of the reverse reaction which equals Kr

[Sam McNeill 1E]

Additionally, kr/k prime=K, the equilibrium constant.

[BCaballero_4F]

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

[Jainam Shah 4I]

K' is the rate constant for the reverse reaction which is why k/k' is the equilibrium constant K

[ShastaB4C]

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

[Adriana_4F]

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.

[Madeline Phan 1E]

k' is the rate of the reverse reaction.

[Ashley Tran 2I]

to clarify, reverse rate means the reciprocal. k'=1/k

[Max Madrzyk Dis 4G]

k' is just for the reverse reaction and kr is for the forward reaction.
