If a gas obeys van der Waals equation(P + a/V2)(V-b) = RTprove that (∂U/∂V) at constant temperature =a/V2.What is the expected boiling point of water at 98.7 kPa.The heat of vaporization is 2258 Jg-1,the molar volume of liquid water is 18.78 cm3mol-1,and the molar ...
Explain why the increase in volume for the isothermal expansion of an ideal gas makes a positive contribution to the total entropy change. What is the change in entropy when: a) 100 g of ice is melted at 0C? b) 100 g of water is vaporized to 100C? Use the values for...
Sulfur dioxide, SO2, is observed to be depleted in the cloud layer of Venus by orders of magnitude compared to its below-cloud abundance1. Gas-phase sulfur chemistry at the cloud top is dominated by the photochemical formation of sulfuric acid, where one photon of light, one H2O molecule, ...
Previous studies have indicated that condensation of low-volatility organic vapor may play an important role in the initial growth of the clusters. However, due to the relatively high vapor pressure and partial molar volume of even highly oxidized organic compounds, the strong Kelvin effect may ...
A gas sample's volume is 50 L at 759.1 torr. What is its volume at 460 torr? The barometer in my lab says the pressure is 0.905 atm. What is this pressure expressed in torr? Explain how to convert a pressure of 912 mmHg to atmospheres. Calculate the molar mass of a gas if 2.30 ...
Together the ΔΨ and ΔpH form the proton motive force (PMF = ΔΨ −ZΔp H, where Z equals 2.3RT/F and R and F are the gas and Faraday constant, respectively, and T is the absolute temperature). (b) Transport of lysine by Lyp1-GFP-...
