Solvolysis of 2- Chloro-2 Methylpropane: Temperature Dependence and the Transition State 2- Chloro-2 Methylpropane (TBC) solvolyzes by the following equation (CH 3 ) 3 CCl + 2 ROH (CH 3 ) 3 COR + ROH 2 + + Cl - (in the presence of water) The kinetics of this reaction are studied by determining the rate of production of hydrogen ions which can be found by measuring the conductance of the reaction solution at different temperature and different solvent mixtures. By comparing the calculated reaction rate constants it is found that as the temperature increases the rate constant increase and this increase is almost the same in all the three different solvent mixtures. (k r at 35°C/ k r at 25°C = 3.52 for 70 % EtOH/ H 2 O solution, k r at 34.61°C/ k r at 24.42°C = 3.00 for 60 % EtOH/ H 2 O solution, k r for 34.97°C/ k r for 24.97°C= 3.36 at 43% EtOH/ H 2 O solution). This is because, according to the Arrhenius equation k = Ae –Ea/RT k is dependant on T because as the temperature rises, the kinetic energy of the molecules
