Why rough surface of a catalyst is more effective?
A rough surface provides more surface area for reactant molecules to collide and interact, increasing the chances of successful reactions. It also presents different binding sites and orientations for molecules to adsorb and react, promoting more diverse reactions. Overall, the rough surface of a catalyst enhances catalytic activity by facilitating more reaction sites and promoting better adsorption of reactants.
How are rates of reaction determine?
Rates of reaction are determined by factors such as concentration of reactants, temperature, presence of a catalyst, and surface area. Increasing the concentration of reactants and temperature generally increases reaction rates, while adding a catalyst can speed up the reaction by providing an alternative pathway with lower activation energy. Additionally, increasing the surface area of the reactants can enhance reaction rates by increasing the number of collisions between particles.
What are 4 things can increase reaction rate?
Increasing temperature, increasing concentration of reactants, using a catalyst, and increasing the surface area of the reactants can all increase reaction rate by providing more energy for collisions between reactant molecules.
What are 5 ways to control a chemical reaction?
Adjusting temperature: Increasing or decreasing temperature can speed up or slow down a reaction. Changing concentration: Adding or removing reactants can affect the rate of the reaction. Using a catalyst: Catalysts can increase the rate of a reaction without being consumed in the process. Controlling pressure: Changing the pressure in a system can alter the rate of a reaction, especially in gas-phase reactions. Altering surface area: Increasing the surface area of reactants can enhance the reaction rate by providing more contact between reactant molecules.
Why is a cell forced to divide?
it's the problem of surface area -to- volume ratio that mean there is no fitting between increasing of surface area and increasing of volume
Why is a catalyst more effective in powdered form?
Higher surface area is available for the chemical reaction.
What can affect effective collision?
Factors that can affect effective collision include the concentration of reactants, temperature, surface area of reactants, and the presence of a catalyst. Increasing the concentration, temperature, or surface area can lead to more frequent and energetic collisions, while catalysts can provide an alternative pathway with lower activation energy for the reaction to occur.
Which methods will usually cause a reaction to speed up?
Increasing the temperature, increasing the concentration of reactants, using a catalyst, and increasing the surface area of reactants are methods that can usually cause a reaction to speed up.

What are three methods to speed up a chemical reaction?
* breaking a solid into something smaller (to increase its surface area) * make the solution more concentrated, * increase the temperature. Other methods for increasing the rate of reaction are incrasing the pressure and adding a catalyst.
Dose crushed ice melt the fastest?
in a sense, you are introducing a catalyst, that is, increasing surface area to the ice. in simpler terms, there is more area for heat to work on, so it does its job faster.

What would increase the reaction rate?
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
Is the earths radius and surface area increasing?
no
4 What happens when you increase the surface area of reactants in a reaction?
Increasing the surface area of reactants in a reaction leads to an increase in the frequency of collisions between particles. This can result in a higher reaction rate due to more effective collisions occurring. Overall, increasing the surface area of reactants accelerates the reaction process.
