What criteria must be met for reactant collisions to result in a successful product?
The reactants must collide with each other
The reactants must collide with enough energy and be in the right positions
The reactants must have enough energy to form the activated complex
How could we make this reaction happen more quickly?
Decrease the concentration of the acid
crush the chalk to increase the surface area
Put the test tube in an ice bath
When surface area is decreased the rate of reaction...
Decreases, because there are LESS possible sites for correct collisions
Increases, because there are LESS possible sites for correct collisions
Decreases, because there are MORE possible sites for correct collisions
Increases, because there are MORE possible sites for correct collisions
Which has more surface area?
Large chunks of chalk
Cube of sugar
Powdered sugar
Small chunks of sugar
A temperature increase causes the particles ......
to slow down
move faster
collide higher
in the right order
How does a catalyst work in speeding up a reaction?
By lowering the activation energy or reaction
by giving them more energy
by making them more available
