The vapour pressures of acetone (A) and acetonitrile (B) can be evaluated by the following Antoine equation. where T is in K and P is in kPa. Assume that acetone and acetonitrile form ideal solutions. For a vapour phase consisting of 40% acetone and 60% acetonitrile, calculate the following: (a) The dew point temperature and concentration of the first drop of liquid at 65 kPa (b) The dew point pressure and concentration of the first drop of liquid formed at 327 K

At approximately atmospheric pressure, methane gas is burned completely with 30% excess air. Both the air and methane enter the furnace at 30 °C saturated with water vapor, and the flue gases leave the furnace at 1500 °C. Calculate how much heat is lost from the furnace per mole of methane. In your solution, show analytically all calculations, including the analytical derivation of the number of moles of water vapor entering the furnace. Use steam tables to determine Psat, and compare your answer with the answer you would obtain using Antoine’s and Wagner’s equations. For the latter, you can determine A, B, C, D as in ** above.

In an electrochemical cell, a metal anode lost 0.195 g while a total volume of 0.04592 L of hydrogen gas was produced. The temperature was 298 K and the barometric pressure was 768.1 mm Hg. At 298 K, the vapor pressure of water is 23.8 mm Hg.  What is the molar mass of the metal?

At a certain temperature and pressure, a 1.00 mol sample of argon gas is pumped into a 22.4 L rigid box that already contains 1.00 mol of nitrogen gas.  We would expect the argon gas to: Group of answer choices decrease the total gas pressure in the box by a factor of 2 occupy the entire 22.4 L volume of the box. increase the total gas pressure in the box by a factor of less than 2. spread out into the box, but the actual volume occupied but he gas cannot be known without pressure information. occupy only 11.2 L of the box.
