Upon defining R = kll(k-1 k,,, and
-
+ kz), these expressions are
= k,.R

k,,,, = k, .Rl(1 + R)

Also, there would be two rates dCldt: (dCldt),= k,.R.A and
-
imation (B 0) leads to k,, and a second (kl 0) makes k., identical with k,,. Since these approximations are consistent with the steady state condition, I see no reason to "disallow" Both novice and expert might be confused or puzzled by a multiplicity . . of published expressions for one steady state rate constant. The purpose of my paper was t o alert readers to an apparent problem and provide its resolution. S. I. Mlller
(dCIdt), = k, .R .(A, - C)/(l+ R)

He then states that, hy applying the steady state assumptions R
