If we rearrange the ideal gas law to be in terms of density: ρ=PM/RT and also consider the affects of the buoyancy force: dP/dy=−ρg, we can combine these equations to find the atmospheric pressure as a function of height above the ground. Do so to find the air pressure at an elevation of 8838 meters, close to the peak of Mt. Everest. You can assume that g is constant all the way up and so is the temperature (273 K)...

AG RT In = RT In Q- RT In K When the system is at equilibrium Q=1 and thus lIn 1-0, so then we can use this equation AG =-RT In K to find the temperature (solve for T). Remember T will be in K. Once we have the temperature we then use the following equation to calculate AG AG= AG+ RT In Q These molecular scenes represent three mixtures in which A2 (black) and B2 (green) are forming AB....
In this lab, you will determine the vapour pressure of ethanol (P) at various temperatures and use this data to find the enthalpy of vaporization (ΔvapH). If a plot of ln P vs. 1/T gives a slope of -9782 K, what is the ΔvapH in kJ/mol? Do not worry about how realistic the value is. Assume R = 8.314 J mol-1 K-1.
