Increasing the temperature of your solution will.......

• Not affect the rate of reaction, collisions are unaffected

• Speed up the rate of reaction due to make MORE collisions

• Slow down the rate of reaction due to there being LESS collisions

What is collision theory?

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

• Molecules need enough energy to collide and react.

• Atoms constantly collide and react.

• The minimum energy needed for atoms to react

Under the collision theory, the particles must collide ____ and ____ for a reaction to occur.

• sufficient rate and sufficient energy
• sufficient surface area and correct orientation
• sufficient catalyst and sufficient energy
• sufficent energy and correct orientation
