Hydrolysis temperature dependence
Web10 feb. 2010 · The effects of temperature and pH on regioselectivity were investigated by analyzing the stereochemistry of hydrolysis products of (1 R ,2 R )- trans -2-methylstyrene oxide between 14−46 °C and pH 6.0−9.0, either catalyzed by the potato epoxide hydrolase StEH1 or in the absence of enzyme. WebTemperature dependence of rate constants Rates of most reactions are vey sensitive to temperature. increase rapidly with increasing temperature. A mere increase of 20 degrees, 298 K to 308 K, for example, can lead to a doublingof the reaction rate. If we recall the kinetic molecular theory (which
