You and a coworker have developed a molecule that has shown potential as cobra antivenom (AV). This antivenom works by binding to the venom (V), thereby rendering it nontoxic. This reaction can be described by the rate law. Rate=k[AV]^1[V]^1. You have been given the following data from your coworker: [V]0=0.20M [AV]0=1.0*10^-4M. A plot of ln[AV] versus t (s) gives a straight line with a slope of -0.32s^-1. What is the value of the rate constant (k) for this reaction?
