Transcribed Image Text:

At 20°C, the hydrolysis of substance A in aqueous solution was carried out, starting of a concentration of 0.05 moles of A per liter. The hydrolysis products ionize, therefore increasing the electrical conductivity of the mixture reactant as the reaction proceeds. The measured values of electrical resistance of the solution were: Tiempo (min) Resistencia eléctrica (ohm) 5 10 20 40 80 150 200 240 7.670 2.058 1.343 0.907 0.675 0.553 0.495 0.476 0.463 0.420 0 a) Determine the kinetic equation of the reaction. b) What temperature should the reactor operate to achieve 90% reagent conversion, in 100 minutes starting from the same initial concentration and given the activation energy of 12,000 cal! mole? Note: Electrical conductivity is a linear function of reagent conversion.
