The azeotrope of the benzene-cyclohexane system has a composition of 53.2 mol% benzene with a boiling point of 350.6 K at 101.3 kPa. At this temperature the vapour pressure of benzene (1) is 100.59 kPa and the vapour pressure of cyclohexane (2) is 99.27 kPa. Determine the activity coefficient for the solution containing 10 mol% benzene

The molar enthalpy of benzene at its normal boiling point (80.09° C) is 30.72 kJ/mol. Assuming that Δ H of vaporization and Δ S of vaporization stay constant at their values at 80.09° C, calculate the value of ΔG of vaporization at 75.0° C, 80.09° C, and 85.0° C. Interpret these results physically.

Calculate the standard heat of reaction for the dehydrogenation of cyclohexane to benzene in the vapor phase. C6H12 = C6H6 + 3 H2 The reactor for this system operates at 70% conversion of cyclohexane. If the feed rate is 4000 kg of pure C6H12 per hour at 100oC, determine the rate of heat addition to or removal from the reactor that is required if the product gases leave the reactor at 300oC.

Benzene is a known human carcinogen. The boiling point of benzene is 80. °C (reference 1). a) Research online to find the short term exposure limit (STEL) for benzene. What does the STEL mean? b) A friend is planning to do an experiment with liquid benzene at 21 °C on the open bench top in a small (18 m3 ) poorly ventilated room (i.e. consider the room to be a closed system for this question). Convert the STEL to vapour...

Benzene and toluene form nearly ideal solutions. The boiling point of pure benzene is 80.1°C. Calculate the chemical potential of benzene relative to that of pure benzene when xbenzene = 0.30 at its boiling point. If the activity coefficient of benzene in this solution were actually 0.93 rather than 1.00, what would be its vapour pressure?

A mixture of 20.0 mol% benzene, 5.00 mol% toluene, and 75.0 mol% air is compressed isothermally at 70 degrees C until condensation first appears. What is the mole fraction of benzene in the condensate? You may assume that air is noncondensable (and thus its vapor pressure is large) and this system obeys Raoult's Law. Note: when solving Antoine's equation it is best to keep all sig figs through calculation and then truncate them at the end. Question options: 0.605, 0.832,...
