You are tasked with determining a good estimate of the pressure and vapor–phase composition for a vapor–liquid–liquid equilibrium system of benzene (1) + water (2) at two temperatures: 303.15 K and 342.35 K. You have the following liquid– liquid equilibrium data for this system at 50°C: x^a₁ = .00051 and x₁^β = .99366 (Griswold et al., 1950). Please provide those estimates while making reasonable assumptions.
