Fill in the blanks to formulate hypotheses to both parts of the lesson question - what is the effect of
temperature on reaction rate and what is the effect of a reactant's particle size on reaction rate?
hypothesis 1 (temperature): if you increase the temperature of a reaction
then the reaction rate will
because particles experience
at higher temperatures

An engineer decides to use a slightly weaker material rather than a stronger material, since she knows that the stronger material can break suddenly. this is an example of what? a choosing a material that will show warning before it fails b using composite materials that combine strength c using a material for multiple applications d using design techniques that increase efficiency and reduce cost
