In hetrogeneous reactions (where the reactants are in different states) the size of the particles of a solid may change reaction rate, since the surface is where the reaction takes place, and the surface area is increased when the particles are more finely divided.
In general, the smaller the particles the faster the reaction
What else can I help you with?
Is changing of color a sign of chemical change?
The change of color may be a sign of a chemical reaction.
Temperature change affects the rate of a chemical reaction by changing the of the colliding particle.?
Temperature change affects the rate of a chemical reaction by altering the kinetic energy of the colliding particles. As temperature increases, particles move faster, leading to more frequent and energetic collisions, which enhances the likelihood of overcoming the activation energy barrier. Conversely, lower temperatures slow down particle movement, resulting in fewer collisions and a reduced reaction rate. Thus, temperature is a critical factor in determining how quickly a reaction proceeds.
Is a frying fish a chemical reaction?
No, frying fish is a physical change, not a chemical reaction. The process involves changing the state of the fish from raw to cooked through the application of heat, without altering its chemical composition.
Is volume a physical property or chemical?
Volume is a physical property.
Changing color of acids is chemical change?
Yes, changing the color of an acid indicates a chemical change because the chemical composition of the acid is being altered. The change in color may be due to a reaction with another substance that results in a new chemical product, indicating a chemical transformation has occurred.
Can you change the rate of a chemical reation by changing the particle size of the reaction?
Yes. when the particle size of the reactants are smaller, the surface area is higher. Thus the probability of the occurrence of collisions in the correct orientation is higher. Hence the rate of the reaction is higher.
Is leaves changing color chemical reaction?
Yes it is chemical change.
Is changing of color a sign of chemical change?
The change of color may be a sign of a chemical reaction.
Is dissolving a physical or chemical reaction?
a physical reaction for the chemical structure is not changing.
Is water changing from liquid to gas a chemical reaction?
No, water undergoing a phase change is a physical change, not a chemical change.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
Why is a phase change not a chemical reaction?
A phase change is a physical change that involves rearranging the molecules in a substance without changing its chemical composition. In contrast, a chemical reaction involves the breaking and forming of chemical bonds, resulting in the formation of new substances with different chemical compositions.
Temperature change affects the rate of a chemical reaction by changing the of the colliding particle.?
Temperature change affects the rate of a chemical reaction by altering the kinetic energy of the colliding particles. As temperature increases, particles move faster, leading to more frequent and energetic collisions, which enhances the likelihood of overcoming the activation energy barrier. Conversely, lower temperatures slow down particle movement, resulting in fewer collisions and a reduced reaction rate. Thus, temperature is a critical factor in determining how quickly a reaction proceeds.
What are the ways rates of chemical change can be changed?
Rate of chemical change can be altered by 1. Changing the temperature. 2. Changing the pressure (if gases are involved). 3. Changing the particle size of a solid reactant. 4. Changing the concentration of a dissolved reactant. 5. Adding a suitable catalyst.
Is volume a physical property or chemical?
Volume is a physical property.
Is a frying fish a chemical reaction?
No, frying fish is a physical change, not a chemical reaction. The process involves changing the state of the fish from raw to cooked through the application of heat, without altering its chemical composition.
Is getting a tattoo a physical or chemical change?
Getting a tattoo is obviously a physical change because you are only changing the appearance of your body. A chemical change is something that is caused by a chemical reaction. Although, the ink being put into your body is a "chemical" it is not changing the structure or function of your body.
