The rate of racemization (which equals the rate of production of R-secondary alcohols if racemization is rate-limiting) is assumed to be first order in the concentration of the S alcohol. If indeed racemization is rate-limiting and all alcohols groups are in the S configuration, (and assuming that the changing polarity of the system plays no significant role) the total rate of reaction (which equals the production of 7?-secondary alcohols) will be first order in concentration of the S alcohol. Therefore, once the 50% conversion threshold has been crossed, a linear relationship should hold between -ln(1 - conversion) and time and a pseudo first order rate constant can be calculated.
