What are the 4 factors that affect the rate of reaction PPT?
The factors that affect the rate of a chemical reaction are : nature of reactants, temperature, concentration, size of particle and catalyst.
What are the four chemical reactions?
Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.
What are the 4 ways to increase the rate of a reaction?
There are 4 methods by which you can increase the rate of a reaction:
- Increase the concentration of a reactant.
- Increase the temperature of the reactants.
- Increase the surface area of a reactant.
- Add a catalyst to the reaction.
What are the factors on which rate of reaction depends?
Factors affecting reaction rate
- Nature of reactants. Reaction rate variation is dependant on which substances are reacting.
- Physical state.
- Rapid kinetics fluorescence.
What is the effect of temperature on rate of reaction?
An increase in temperature causes a rise in the energy levels of the molecules involved in the reaction, so the rate of the reaction increases. Similarly, the rate of reaction will decrease with a decrease in temperature.
What are the characteristics of chemical reaction?
The characteristics of a chemical reaction are: Evolution of gas, Formation of a precipitate, Change in colour, Change in temperature, Change in state etc.
What are the 5 ways to change the rate of a chemical reaction?
5 ways to increase reaction speed
- Heat it up to speed it up: increasing temperature.
- The opposite of social distancing: increasing concentration or pressure to increase reaction speed.
- Divide and conquer: decreasing particle size to increase reaction speed.
- Pro gamer move: dropping a catalyst.
What factors influence the reaction rate of a chemical reaction?
There are many factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.
How does kinetic energy affect the rate of chemical reaction?
As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate.
How does temperature affect the rate of reaction between particles?
The frequency of particle collisions. The proportion of particle collisions that are successful. An increase in temperature will lead to an increase in reaction rate. Reactant particles move around more, resulting in a greater frequency of collisions.
What are chemical reactions?
What Chemical Reactions Are Elements are the basic substances that make up matter in the universe. Each element is a chemical. Elements that form bonds are called molecules. An oxygen molecule, for example, has two oxygen atoms. Chemical reactions occur when molecules interact and change.
