Collision Theory Recap

Front

Collision theory

Back

Molecules must collide in the correct orientation with enough energy to bond.

Front

What is the rate of reaction?

Back

The time it takes for a reaction to occur.

Front

What is the purpose of a catalyst?

Back

Helps to speed up a reaction

Front

Increasing the temperature of your solution will...

Back

Speed up the rate of reaction

Front

Decreasing the concentration of a substance will usually...

Back

Slow down the reaction

Front

Which has more surface area? Large chunks of chalk, Cube of sugar, Powdered sugar, Small chunks of sugar

Back

Powdered sugar

Front

If you shrink the container size that your gas substance is in, what will happen to the reaction rate?

Back

The reaction rate will speed up

Front

With the increase in temperature, the average kinetic energy of the molecules increases, leading to a decrease in number of collisions per unit time.

Back

False

Front

More collisions correspond to a:

Back

Faster reaction rate

Front

What criteria must be met for reactant collisions to result in a successful product?

Back

The reactants must lightly collide with enough energy in the correct orientation.
