Which statement about the factors that affect reaction rates is false? Decreasing the concentrations of the reacting particles decreases the chance of collision. A collision with poor orientation requires a higher activation energy than a collision with optimum orientation. Increasing the pressure in a gaseous reaction increases the chance of collision. A reaction occurs every time particles of the reactants collide. Increasing the temperature increases the reaction rate.

Question
Which statement about the factors that affect
reaction rates is false?
Decreasing the concentrations of the
reacting particles decreases the chance of
collision.
O A collision with poor orientation requires a
higher activation energy than a collision
with optimum orientation.
Increasing the pressure in a gaseous reaction
increases the chance of collision.
A reaction occurs every time particles of the
reactants collide.
Increasing the temperature increases the
reaction rate.

Why does an increase in concentration increase the
rate of reaction?
Collisions become more effective.
The number of collisions increases.
O The activation energy decreases.
The average kinetic energy increases.
When there are more molecules in the
container, they all speed up.
