12685080471	Chemical Kinetics	the speed of the reactions (reaction rates) and the way in which the reactions occur	0
12685080472	How does chemical kinetics occur?	In a series of smaller steps involving the collision of one or two particles at a time	1
12685080473	The speed of reactions depend on the ________________ of collisions and the __________________ of those collisions.	number effectiveness	2
12685080474	What two things must happen in order for a collision to be effective?	the particles must have enough energy and they must be oriented properly. (alignment)	3
12685080475	Increase in effective collisions=	Increase in rate of reaction	4
12685080476	In solutions, __________________ compounds tend to react more QUICKLY than _________________ compounds because fewer bonds need to be rearranged.	ionic covalent	5
12685080477	As concentration of a reactant increases, the rate of reaction.....	increases	6
12685080478	As pressure increases, the rate of the reaction...	increases	7
12685080479	As surface area increases, the number of particles that collide increase, as well as the...	reaction rate	8
12685080480	As temperature increases, the rate of the reaction...	increases	9
12685080481	Catalysts lower the _________________ _____________ of a reaction by providing an alternative reaction pathway	activation energy	10
12685080482	True/False: The overall reaction and the value of delta H, the heat of the reaction, remain unchanged by its presence.	TRUE	11
