18 Questions
What determines whether a reaction will occur between two particles that are colliding?
The energy of the particles and the correct orientation of collision
When two particles collide, what can occur if a chemical reaction happens?
The bonds between particles are broken and reformed
In a chemical reaction, what are the substances that enter and are changed called?
Reactants
What is needed for two substances to react according to the collision theory?
Activation energy and correct orientation of collision
What is a factor that determines whether a reaction will occur between two colliding particles?
The energy and orientation of collision
Which part of a chemical equation represents the substances that are formed?
Products (right side)
What is the primary reason why increasing the temperature results in a faster chemical reaction?
The increased kinetic energy of the particles leads to more collisions between them.
How does increasing the concentration of reactants affect the rate of a chemical reaction?
Increasing the concentration increases the reaction rate.
Which of the following is NOT a factor that determines the rate of a chemical reaction?
Pressure
Which of the following is the most important factor in determining whether a chemical reaction will occur?
Activation energy
How does the particle size of a solid reactant affect the rate of a chemical reaction?
Smaller particle size increases the surface area, leading to a faster reaction.
How does the orientation of collisions between reactant particles affect the rate of a chemical reaction?
Properly oriented collisions increase the reaction rate.
What is the primary factor that determines whether a chemical reaction will occur when particles collide?
The orientation of the particles during the collision
What is the term used to describe the minimum energy required for a chemical reaction to take place?
Activation energy
Which of the following statements is true about the rate of a chemical reaction?
The rate of a reaction is a measure of both the decrease in concentration of reactants and the increase in concentration of products over time
What happens when the temperature of a chemical reaction is increased by 10°C?
The reaction rate doubles
Which of the following conditions is necessary for a chemical reaction to occur?
The particles must come into contact with one another or collide
If the energy of the colliding particles is less than the activation energy, what is likely to happen?
The particles will bounce off each other unchanged
Learn about the key aspects of collision theory in chemistry, which explains how particles must meet certain criteria for a chemical reaction to occur. Explore the importance of particle collision, proper alignment, and energy requirements in initiating a reaction.
