Document Summary

Gas pressure: force exerted onto the surface on an enclosure due to the large number of impacts of gas molecules w/ each other and the container walls. Whatever has stronger intermolecular force will be liquid at room temp and the other will be gas when comparing. When comparing rst look at molar mass but if they"re the same then look at intermolecular forces. Determine miscibility by seeing what is polar and polar. 2 things around central atom" it"s linear electron geometry. 3 things aca is trigonal planar(e geo)- 1 lone pair is bent- molecular geo. 4 things aca is tetrahedral(e geo)- 1 lone pair is trigonal pyramidal or 2 lps is bent- molecular geo. Periodic table is up and to the left arrows. Increasing concentration of reactants rate will go down. Low temp particles have less energy and collisions are less frequent making fewer effective collisions. High temp particles have more energy collisions are more frequent so more effective collisions.
