Document Summary

Due: wednesday, april 1, 2020: adiabatic energy balance. The elementary, irreversible liquid-phase reaction a + b c is carried out adiabatically in a. C p,c = 30 cal/(mol k), h rxn = -6 kcal/mol a at 273 k, and conversion x a = 0. 80. Adiabatic energy balance equation: i c p,i (t - t 0 ) = -x a [ h rxn + c p (t - t r )] Given a = b = 1, c = 0, i c p,i (t - t 0 ) = 25 cal/(mol k) * (t - 300) Solve for c p = c p,c - c p,b - c p,a = 5 cal/(mol k) Plug in values: 25 (t - 300) = -0. 80 [-6000 + 5 (t - 273)] Therefore t = 462 k: solve for reactor volume v given k = 0. 01 l/(mol s) at 300 k and activation energy.
