G10 Unit 28 The Collision Theory Flashcards
defined by the number of reactions related to the amount of reactants being changed into products over time
Reaction rate
Reaction rate can be expressed in the units of
molarity per second, M/s
the rate of a chemical reaction is directly proportional to the number of collisions between the reactants
presents the conditions that must be satisfied for a chemical reaction to take place
collision theory
Reaction rate is usually _ with the amount ofeffective collisionsbetween molecules in a given span of time.
proportional
Reaction rate is usually proportional with the amount of_ collisionsbetween molecules in a given span of time.

Conditions of Collision Theory
Orientation
Energy Requirement
They must be properly _ when they collide.
oriented
This _ of the reactants will affect which part of the reactant will collide with another reactant, and only properly oriented compounds or elements will successfully form a product.
orientation
only properly oriented compounds or elements will successfully form a _
product
Aside from proper orientation, the reactants will need to collide at a minimum specific _ in order for the reaction to occur.
speed
The reactants must then be energetic enough to be equal to or to surpass the _ _.
activation energy
the minimum energy required to break the existing chemical bonds of the reactants
Activation energyorEa
Factors that Affect the Rate of Collision
concentration of reactants,
temperature, and
particle size.
An increase in the _ of reactants increases the rate of reaction.
When the _ is high, more particles are present.
concentration
An increase in _ increases the rate of reaction.
Higher _ will generally lead molecules to move faster than lower temperatures.
