How does an increase in reactant concentration affect the rate of reaction?
It leads to more frequent collisions, which increase reaction rate.
How does increasing the surface area of a solid reactant affect the energy of molecular collisions?
Reactions depend on molecular collisions. If a solid reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area, the faster the molecular collisions, which in turn increases the rate of reaction.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Why can grinding a solid into a fine powder increase the rate of reaction?
Grinding a solid into a fine powder increases the rate of reaction by increasing its surface area. A larger surface area allows more collisions between reactant particles, which enhances the likelihood of successful interactions and reactions. Additionally, the smaller particle size can improve the dispersion of the solid in a mixture, further facilitating contact with other reactants. This leads to a faster overall reaction rate.
Does increasing pressure affect reaction rate?
If the pressure increase the number of intermolecular collisions increase and so the reaction rate. This is valid for gases.
Not increase the rate at Which a solid dissolves?
Decreasing temperature would not increase the rate at which a solid dissolves

How does heat affect the rate of the reaction?
Increasing the temperature the reaction rate increase.
What does temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Why is the solution boiled after adding excess hydrochloric acid to the solid hydrate?
to remove carbondioxide from the solution and also to increase the rate of reaction
How does increasing the surface area of a solid reactant affect the energy of molecular collisions?

What are three ways to increase the rate at which particular reaction proceeds?
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
How can you increase the rate of catalase reaction by using the same liver?
To increase the rate of catalpas reaction by using the same liver is simple. It is the biological catalyst that alters the rate of reaction that changes itself.
Does the mass of a solid reactant affect the reaction rate?
The mass of a solid reactant typically does not directly affect the reaction rate, as it is the surface area of the solid that usually plays a more critical role in determining the rate of reaction. However, in some cases, a higher mass of solid reactant may lead to longer mixing times, which can indirectly affect the reaction rate.
Does removing a catalyst increase the rate of a reaction?
No in the vast majority of cases it reduces the rate of reaction.
Is temperature essential in determining the reaction rate?
yes, as the reaction rate increases with increase in the temperature
