Document Summary

Due: wednesday, february 19, 2020: phase changes. The elementary, irreversible gas phase reaction a 2b + c takes place at p = 5 atm, t = 350 k. The specific rate constant is k = 0. 001 s -1 . The feed consists of 5 mol a/hr and 5 mol c/hr. a. F t = 2f a0 + 2f a0 x a = f t0 (1 + x a ), therefore v = v 0 (1 + x a ) Cstr design equation: f a0 - f a = -r a v. Elementary reaction: -r a = kc a = k(f a /v) = kc a0 (1 - x a )/(1 + x a ) F a0 x a = kvc a0 (1 - x a )/(1 + x a ) k 0 = x a (1 + x a )/(1 - x a )
