The mass balance will contain V. Step #3: Apply the gas mass balance around the system. ( ) dt d rV = r iF i rF w = r 60 540 rF w (E-1) Since the temperature and pressure of the inlet, stored, and outlet gases are equal and nearly constant throughout the given time period, r = r i, Eq. (E-1) becomes .

total mass (m). When the sink is described in this first order form we can rewrite the mass balance as: d[M] / dt = Q k [M] At steady state, when d[M] / dt = 0, [M] / Q = mass present/input = 1/k = This equation predicts an inverse relationship between elemental reactivity (k) and residence time as k
