Which would have a higher vapor pressure: ethanol (C 2 H 5 OH) or dimethyl ether (CH 3 OCH 3 )?

Hey everyone. So here it tells us that a satellite which is CH three CH. O. Has a normal boiling point of 20.2 degrees Celsius. Based on the figure below, identify whether a satellite or ethanol will have a higher vapor pressure. Alright, so looking at this chart, we can see ethanol is here And it has a normal boiling point of 78.3°C. So what's boiling point is higher? We're going to say here, the higher your boiling point, this correlates to a lower vapor pressure. Mhm. Okay, so remember that vapor pressure is the equilibrium that's established between condensation and vaporization. So if you're boiling point is higher, it takes longer for you to become vaporized, which means it'll take longer for you to establish an equilibrium between vaporization and condensation. So since ethanol has a higher boiling point, it would have the lower vapor pressure. And that means that a satellite is the one that should have the higher vapor pressure. So a satellite is the answer for this particular question.
