Intercepting reactions lying above ( faster rates at the same substrate concentration ) the parent reactions on the rate vs . substrate concentration plot, are indicative of catalyst deactivation under reaction conditions; further experimentation is necessary to distinguish product inhibition from other forms of catalyst death.
12.
While same-excess experiments as described above cannot attribute catalyst deactivation to any particular cause, product inhibition can be probed by further experiments in which some initial amount of product is added to the intercepting reaction ( designed to mimic the amount of product expected to be present in the parent reaction at the same substrate concentration . ) A perfect overlay of the rate vs . substrate concentration plots under same-excess-same product conditions indicates that product inhibition does occur under the reaction conditions used.
