Why does a reaction proceed faster when the reactants have greater surfaces area?
Wiki User

A greater the surface area will cause the reaction will proceed faster because there are more available sites where another reagent or catalyst can "attack" the reactant.

How is a catalyst different from the reactants and products of a chemical reaction?
Unlike reactants, catalysts are not used up during a reaction. They merely speed up the reaction (or allow it to proceed).
If a reaction is at equilibrium and you add reactants what happens?
If you continuously add reactants even after the reaction has attained the equilibrium then according to Le Chatelier's principle, the reaction will again proceed in forward direction in order to neutralise the reactants and once again the attain the state of equilibrium.
What happens after you add just reactants to a reversible reaction?
In a reversible reaction, the reactants and products become to a dynamic equilibrium after some time. after gaining this equilibrium, when more reactants are added the equilibrium breaks. So according to the Le Chetelier principle, the reaction will proceed until the equilibrium is gained.
The direction in whick a reversible reaction will proceed can be predicted from the laws of?
it dependes upon the initial ratio of molar concentration of products to reactants higher the ratio reaction will proceed in the reverse direction and vice versa
How is the rate constant related to concentration of reactants?
As a chemical reaction proceed the concentration of the reactants keep on decreasing while those of the products keep on increasing how ever the rate of the reaction is also found to decrease this show that the rate of the reaction is directly related to the concentration of reactants
What may be expected when K?
The concentration of one or more of the products is small, the reaction will not proceed very far to the right, and the reaction will generally form more reactants than products.
What may be expected when K 1.0?
The concentration of one or more of the products is small, the reaction will not proceed very far to the right, and the reaction will generally form more reactants than products.
Why do catalyst allow the chemical reaction take place at 0 Celsius?
When reactants are joined by a catalyst, they no longer have to collide with much energy to react. Thus, with the catalyst present the reaction can proceed at very low temperatures.
What does grinding solid reactants into powder - do to the reactant particles?
The powdered form of a solid reactant has an aggregate surface area that is many times greater than the solid blockfrom which it came. This makes any reaction proceed faster and more efficiently, usually resulting in enhanced yield as well.
What does it mean when are reaction is spontaneous?
The reaction happens by itself.
Define five ways you can speed up or slow down a reaction?
Changing the temperature of the reaction can speed it up by increasing molecular collisions and kinetic energy. Adding a catalyst can speed up a reaction by lowering the activation energy required for the reaction to proceed. Increasing the concentration of reactants can speed up a reaction by providing more reactant molecules to collide and react. Changing the surface area of solid reactants can speed up a reaction by exposing more reactant surface area for collisions to occur. Adjusting the pH of the reaction environment can speed up or slow down a reaction by affecting the ionization state of reactants and the reaction rate.
Which reaction cannot proceed without an activation energy?
An exergonic reaction
