1. Determine the second-order rate constant for the disappearance of A in the gas phase reaction 2AR.
When hold the pressure at a constant, the volume of the reaction mixture V, starting with V0 containing
80% of A at 0.8 mol/L and 20% of R at 0.2 mol/L, decreases by 20% to 0.8 V0 in 2 min.
(Hint: integral method for varying volume second-order reaction on page 99)
2. For an isothermal single-phase flow reactor operating at steady-state and constant pressure. Given a
gaseous feed CA0 = 100, CB0=150, A+2BR, at CA=70. Find XB.
