Now, let's begin by describing the rate law of this reaction going this way. So if we're going this way, then the rate law is given by V knot. The rate of this reaction is equal to Kcat. This rate constant multiplied by the concentration of the reactant, in this case, that enzyme substrate complex. And let's call this equation number one. Now, if you recall our discussion, our derivation of the of the Michaelis methane equation, we basically used the steady state conditions.
