Does the surface area of a chemical reactant affect the rate of the chemical reaction?

If the surface area of a reactant is increased: more particles are exposed to the other reactant. there is a greater chance of particles colliding, which leads to more successful collisions per second.

What are the three factors that affect the equilibrium of a system?

Changes in concentration, temperature, and pressure can affect the position of equilibrium of a reversible reaction.

How will the rate of the reaction be affected when a surface area of the reactant is reduced by catalyst is added in a reversible reaction?

When solids and liquids react, increasing the surface area of the solid will increase the reaction rate. The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.

Why does increasing the surface area of the reactants increase the rate of reaction?

Increasing the surface area of a reactant increases the frequency of collisions and increases the reaction rate. Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.

How does surface area affect the rate of reaction experiment?

When the surface area is decreased the reaction, rate will slow down because, the chemical can only react with the outside of the substance and chew away at it until there is none left, but with an increased surface area there is more atoms to react with compared to a small surface area.

Does surface area affect equilibrium?

To a first approximation changing the surface area has no effect on the final equilibrium condition. If the surface area is larger, then a reaction will reach an equilibrium more quickly, but the final position reached is the same as with a smaller surface area.

How does the increase of concentration of the reactants affect equilibrium?

Le Chatelier’s principle predicts that equilibrium will shift to decrease the concentration of reactants. When the concentration of reactants is increased, the equilibrium shifts to the right and there will be more product than before. There will also be more reactants than before (more reactants were added).

How will the rate of reaction be affected when a surface area of the reactant is reduced?

The surface area of reactants affects the rate of reaction. If the size of a particle is small, the surface area will be more and this increases the speed of heterogeneous chemical reactions.

How will the rate of reaction be affected when?

Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.

What does not affect the equilibrium constant?

Presence Of Catalyst : A catalyst has no effect on the value of the equilibrium constant of a reaction. This is because a catalyst affects the rates of forward and backward reactions to the same extent. A catalyst helps in attaining the state of equilibrium faster.

What changes the state of equilibrium during a chemical reaction?

Change in temperature: This alters the state of equilibrium for only those reactions which are either endothermic OR exothermic. Every such reaction is made up of 2 opposing reactions i.e., if the forward reaction is exothermic, the backward reaction will be endothermic and vice versa.

What are the factors that affect the equilibrium of a system?

A system in equilibrium is affected by the following factors: Change of concentration of any reactant or product. Change of temperature of the system. Change of pressure of the system. Addition of catalyst. Addition of some inert gas.

Why does the equilibrium constant remain the same with a catalyst?

The value of the equilibrium constant also remains the same because, the catalyst increase the rate of forward reaction and the rate of backward reaction by the same amount. What is the effect of adding inert gas?

How does temperature affect equilibrium constant of endothermic reaction?

Further, it has been found that the value of equilibrium constant of an endothermic reaction increases and that of an exothermic reaction decreases with increase in temperature. The equilibrium constant, K is to be kept constant.
