Decreasing particle size collision frequency of reactants?
increases
What is Planetary Collision Theory?
The Collision Theory states that the rate of molecules colliding with sufficient kinetic energy successfully is proportional to the collision frequency multiplied by the fraction of collisions. The assumptions are that the molecules are spheres and traveling in straight lines.
How are the concentration of the reactants and reaction rate related?
rate laws a+the higher the concentration = more particles = higher chance of a collision happening = higher/faster reaction rate
Which factor can decrease the rate of a chemical reaction?
concentration of product. concentration of poisons.
The substances present before a reaction occurs are called A. molecules B. products C. elements D. reactants E. chemicals?
The reacting particles are called reactants.
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
How does the factor concentration affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
How does concentration factors affect reaction rate?
increasing concentration increases rate of reaction as there are more particles so there is a larger chance of collision,it increases the probability of collision of the reactants.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
Decreasing particle size collision frequency of reactants?
increases
Does every collision between reacting particles leads to products?
For a reaction to take place, the reactants must have sufficient energy and have correct orientation when they collide. So, the reason why all collisions don't lead to reaction is that the collisions do not satisfy these conditions.
How does the concentration of reactants affect the rate of a reaction.?
Increasing the concentration increases the molecules' collision frequency.

They contain different combinations of particles.
