Concentration of reactants
Why is proper orientation important for effective collisions between molecules?
To facilitate successful reactions
What role does the collision theory attribute to molecules in a chemical reaction?
Molecules must collide to react
What is concentration with regard to chemical reactions?
Amount of solute per unit volume
What is the relationship between the concentration of reactants and the rate of a chemical reaction?
The rate of reaction is directly proportional to the concentration of reactants
What is the effect of increasing temperature on the rate of a chemical reaction, according to collision theory?
Increasing temperature increases the kinetic energy of the molecules, increasing the rate of reaction
What is the relationship between surface area and particle size for solids?
As particle size decreases, surface area increases
