The second term, N²/k is the negative growth from used capacity.
Webthe rate of a reaction depends on the rate constant and concentration R=k[A][B].. the rate constant according to Arrhenius is as u stated. from ur equation u can see that concentration doesnt affect k but affects R. Temperature affects k and k affects R so, temperature affects both while concentration affects only Rate of reactions. WebFeb 12, 2024 · The reason for this is because the reactants are decreasing as a function of time, the rate would come out to be negative (because it is the reverse rate).
