(a) (i) If in a kinetics experiment, the rate of hydrolysis of ethyl acetate (EtAc) was observed to proceed with a rate constant of 3.8 x 104s' at 24.5 °C, calculate the new slope of a plot of In[EtAc], versus t when the temperature is increased to 32.1°C, if the activation energy barrier for this process is 192.3 kJ mol". (ii) Describe a simple method by which the rate of hydrolysis of ethyl acetate, a simple organic ester, could be monitored. (b) (i) Starting from the Eyring equation in the form kk T. k = Show how the entropy and enthalpy of activation could be determined.
