(gpt/ai wrong answer not allowed)
A gas mixture at 1.0 atm pressure abs containing air and CO₂ is contacted in a single-stage
mixer continuously with pure water at 293 K. The two exit gas and liquid streams reach
equilibrium. The inlet gas flow rate is 100 kg mol /h, with a mole fraction of CO₂ of yA2=0.20.
The liquid flow rate entering is 300 kg mol water/h. Calculate the amounts and compositions
of the two outlet phases. Assume that water does not vaporize to the gas phase.
(At 293K, the Henry's Law constant is 0.142*104 atm/mol frac)
