1.A study of reaction __ is called chemical __.
2.Reaction rate refers to how quickly or slowly the ___ disappear and the ___ appear.
3.it is measured in terms of the ___ of the reactants.
4.If a reaction is to occur, reacting particles must first ___ and this ___ must be effective.
5.What are two characteristics of an effective collision?
This is what I got
1. Rates, reaction
2. Reactants,products
3. I don't know what this is
4. Collide,process
5. Would it be collision orientation?and one other one

Do your own homework

I did I was asking if it was right and help on one part

I have the first three I'm also in chemistry with the same problems.
1. A study of reaction rates is called chemical reactions.
2. Reaction rate refers to how quickly or slowly the reactants disappear and the products appear.
3. If a reaction is to occur, reacting particles must first collide and this collision must be effective.
