Activated-complex theory of chemical kinetics?
The activated complex theory, also known as the transition state theory, describes the process of chemical reactions by considering the formation of an activated complex or transition state. In this theory, the reactants need to overcome an energy barrier in order to transform into the activated complex, which then breaks down to form the products. This theory helps in understanding reaction rates and factors that influence the kinetics of chemical reactions.
Who thought of the collison theory?
The collision theory was developed by Max Trautz and William Lewis in the early 20th century. They proposed that chemical reactions occur when reactant molecules collide with sufficient energy and proper orientation. This theory laid the foundation for understanding reaction rates and kinetics in chemistry.
What do molecular clocks have to do with reaction rate?
Molecular clocks are tools used to estimate the timing of evolutionary events based on the mutation rates of genes over time. While they primarily focus on genetic changes, the concept of reaction rates in molecular biology relates to how quickly these changes can occur under specific environmental conditions. In essence, both molecular clocks and reaction rates reflect dynamic processes at the molecular level, where reaction rates can influence the frequency of mutations and, consequently, the reliability of molecular clocks in tracking evolutionary timelines.
How does the kinetic Theory and Brownian motion influence reactants?
The kinetic theory explains that particles in a substance are in constant motion, which affects the frequency and energy of collisions between reactants, thereby influencing reaction rates. Brownian motion, the random movement of particles in a fluid, contributes to the dispersion and mixing of reactants, enhancing the likelihood of interactions. Together, these principles highlight how temperature and particle movement can impact chemical reactions, with higher temperatures increasing kinetic energy and collision rates, leading to faster reactions.
Decreasing particle size collision frequency of reactants?
Decreasing particle size increases the surface area available for collision, leading to a higher collision frequency of reactants. Smaller particles move more freely and are more likely to collide with each other, increasing the chance of successful collisions and promoting faster reaction rates.
How does collision theory relate to equilibrium?
Collision theory is when mollecules must collide with one another in order to cause a reaction. In a succesful collision, old bonds are broken as new bonds are formed. Equilibrium is a state in which forces cancel one another.
What factors the collision theory?
The collision theory states that for a chemical reaction to occur, reactant molecules must collide with sufficient energy and proper orientation. Factors that can influence reaction rates according to this theory include temperature (increased temperature increases the kinetic energy of molecules), concentration of reactants (higher concentrations lead to more collisions), and the presence of a catalyst (which can lower the activation energy required for the reaction).
What is the relation between Arrhenius theory and Vaunt Hoffa equation?
Arrhenius theory explains the temperature dependence of reaction rates in terms of activation energy, while Van't Hoff equation relates the equilibrium constant of a reaction to temperature changes. Both concepts involve the role of temperature in affecting the behavior of chemical reactions, with Arrhenius theory focusing on reaction rates and activation energy, while Van't Hoff equation focuses on equilibrium constants.
What is collition theory?
Collision theory is a concept in chemistry that explains how chemical reactions occur through the interaction of molecules. It posits that for a reaction to take place, reactant particles must collide with sufficient energy and the correct orientation. The energy required to initiate a reaction is known as the activation energy. This theory helps to understand factors that influence reaction rates, such as concentration, temperature, and the presence of catalysts.
What role does the gas constant play in the Arrhenius equation for calculating reaction rates?
The gas constant in the Arrhenius equation helps to account for the effect of temperature on reaction rates. It is a constant value that relates the energy of the reacting molecules to the rate of the reaction.

I'm sorry, but I can't provide specific answers to assessment questions from Explore Learning or any other educational platform. However, I can help explain key concepts related to collision theory, such as how the frequency and energy of particle collisions affect reaction rates.

Use collision theory to explain why reactions should occur more slowly at lower temperatures?
At lower temperatures, the kinetic energy of particles is lower, resulting in fewer collisions between reactant molecules. This reduces the frequency of effective collisions necessary for a reaction to occur. Additionally, the lower temperature decreases the likelihood of reactant molecules overcoming the activation energy barrier required for a successful reaction.
What causes pressure changes of reactants to affect the reaction rate?
The frequency of collisions is changed.

What will not affect reaction rates?
Astrological signs will not affect reaction rates.
