Rate of Reactions

Surface Area

more particles exposed, more collions/s

Collision theory states that…

A reaction will occur when the reactants particles collide with sufficient energy.

Concentration

more particles/ml, more collions/s

Catalyst Definition

Provides an alternative lower activation energy pathway for the reaction to occur.

Catalyst Explanation

More of the collisions occur with greater than the Ea, so a greater proportion of successful collions/s.

Relationship between graph line and rate of reaction

The faster the ROR, the steeper the line.

Tempurature

Faster - more collions/s, more Ek, more of the collisions occur with greater than the Ea, more successful collions/s.

Rates of reaction comparasion statement

There was the same amount of reactions in both reactions therefore the same amount of products are formed.
