(b) The ring opening of epoxides (oxirancs) with thiols is catalysed by sodium hydroxide in aqueous media at 300 K. For a typical reaction, the pH-rate profile, between pH 8 and 14 is linear with a slope of +1. What type of catalysis is involved here - give an appropriate rcaction mechanism and state how you would establish the numerical value of the second order rate-constant for the process from the pH-rate profile. Your answer should include a definition of the term pH-rate profile and a statement of the accompanying rate equation for the process. R'-SH NaOH OH R2 Water R1-S R2
