Specific Heat and Collision Theory

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

• The reaction rate will stay the same (same # of collisions)

• The reaction rate will speed up (more collisions)

• The reaction rate will slow down (less collisions)

Decreasing the concentration of reactants will usually........

• Slow down the reaction (less collisions)

• Speed up the reaction (more collisions)

• Have no affect on the reaction

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
