Problem 4: A bottle of perfume is opened in a room in which the air is perfectly still. Assume Dperfume = 5 x 10-6m²/s. Estimate the time t that it will take for the perfume molecules to diffuse a distance L=5 m across the room. Don't be surprised if the time is very long. Diffusion is very slow. Almost always, gases mix due to stirring or convection, long before diffusion mixes them.

I posted 3 graphs. What is the apparent kinetic orderof each data? it seems all 0 order for me... is that correct? And what are the units of slope and RMSE? I guess slope is Abs/s and RMSE is just abs. RMSE is in the picture that's the only information I have,,,, Graph 1 ln(Absorbance) VS T[s] Graph 2 Absorbance VS T[s] Graph 3 Absorbance VS T[s] Please explain me in detail!! I need a help!! Thank you very much
1.) A gas at 250 K and 1520 kPa has a molar volume 12% smaller than that calculated from theperfect gas law. Calculate (a) the compression factor under these conditions, and (b) the molarvolume of the gas. Answer: [0.88; 1.20] 2.) At 300 K and 2026 kPa, the compressibility factor of a gas is 0.86. Calculate the volume occupied by 8.2 mmol of the gas under these conditions. Answer: [8.68 x 10^-3]

Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the equation PV = C, where C is a constant. Suppose that at a certain instant the volume is 100 cm3, the pressure is 200 kPa, and the pressure is increasing at a rate of 20 kPa/min. Find the rate at which volume is changing at this instant? cm3/min
Solve correctly please, should correct (Gpt/Ai wrong answer not allowed). A snorkeler takes a syringe filled with 24 mL of air from the surface, where the pressure is 1.0 atm, to an unknown depth. The volume of the air in the syringe at this depth is 8.5 mL .If the pressure increases by an additional 1 atm for every 10 m of depth, how deep is the snorkeler?
