What is the rate of reaction?
How much energy is needed for a reaction to occur.
The energy required to break a bond.
The time it takes for a reaction to occur.
Collision Theory
Increasing the temperature of your solution will.......
Not affect the rate of reaction.
Speed up the rate of reaction
Slow down the rate of reaction
Which has more surface area?
Large chunks of chalk
Cube of sugar
Powdered sugar
Small chunks of sugar
The collisions which bring about a chemical reaction are called:
Consistent collisions
Normal collisions
Hard collisions
Successful collisions
What criteria must be met for successful reaction to occur?
The reactants must collide with each other
The reactants must collide with enough energy and at the right angle
The reactants must have enough energy to collide with
Every collision is successful
Why does a higher concentration increase the rate of reaction?
it increases the amount of reactant particles in the same volume
it decreases the amount of reactant particles in the same volume
it increases the kinetic energy of particles
it decreases the frequency of particle collisions
