Steady State - Definition, Approximations for Complex Reactions

Webrate law is valid so long as the concentration of C has reached a steady state. We can consider a couple of limiting cases. In the limiting case where k −1 is much smaller than k 2, we can neglect k −1 in the denominator and the rate law simplifies to give an overall rate equal to k 1 [A] [B], i.e. sharran proudfoot https://ruttiautobroker.com
