Because of an increase in surface area.
Think about it. If you have a brick of something, you have 6 surfaces on which something else can interact with to cause a reaction. If you grind up the brink into thousands of little particles, you have thousands of little surfaces, as opposed to 6, that you can react with.

What reaction happens when baby powder is mixed with iodine?
Baby powder, or talcum powder, is starchy in composition. When combined with iodine, the powder reaction will be a change in color to a dark blue, purple, or blackish hue depending on the amount used.
What happen when ethanol is heated with bleaching powder and water?
When ethanol is heated with bleaching powder (calcium hypochlorite) and water, it can undergo oxidation to form acetaldehyde. The bleaching powder provides the chlorine necessary for this oxidation reaction to occur. This reaction is typically used in organic chemistry for the transformation of alcohols into aldehydes or ketones.
Is used to lower the energy required to make a reaction take place It makes chemical reactions go faster without being consumed?
A catalyst is used to lower the activation energy needed for a chemical reaction to occur. It increases the reaction rate without being consumed in the reaction itself.
A 5.0-gram sample of zinc and a 50-milliliter sample of hydrochloric acid are used in a chemical reaction Which combination of these samples has the fastest reaction rate?
The faster reaction rate will likely occur when the zinc and hydrochloric acid are in a greater contact surface area. In this case, the 5.0-gram sample of zinc will have a higher surface area compared to the 50-milliliter sample of hydrochloric acid. Thus, the combination with the fastest reaction rate is the 5.0-gram sample of zinc.
What makes a reaction proceed faster without itself being used up during the reaction?
catalyst
Why is KNO3 used in gun powder?
KNO3 (potassium nitrate) is used in gun powder as an oxidizing agent. When gun powder is ignited in a confined space, it rapidly decomposes to release gases that build pressure, propelling a projectile like a bullet out of a firearm. Potassium nitrate supplies oxygen for this reaction to occur.
What happpens to the speed of a chemical reaction when a catalyst is present?
When a catalyst is present in a chemical reaction, it increases the reaction speed by lowering the activation energy required for the reaction to occur. This allows more molecules to collide with enough energy to react, leading to a faster formation of products. Importantly, the catalyst remains unchanged at the end of the reaction, allowing it to be used multiple times.
Is enzymes slow the rate of reaction?
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
What is baby powder reaction in vinegar?
When baby powder, which typically contains talc or cornstarch, is mixed with vinegar, a mild reaction occurs primarily due to the acetic acid in vinegar interacting with the components of the powder. While there may not be a dramatic chemical reaction, the vinegar can cause the powder to clump or dissolve, altering its texture. This reaction is often used in educational demonstrations to illustrate changes in states of matter or to explore basic acid-base interactions.
How do enzymes function speeding up in a chemical reaction?
Enzymes function by lowering the activation energy needed for a chemical reaction to occur, which speeds up the reaction. They achieve this by providing an alternative pathway for the reaction to proceed more easily. Enzymes do not get consumed in the reaction and can be used repeatedly.
Is a catalysed reaction the same as a chemical reaction?
Yes, the only difference is that a catalyst is used to change the activation energy of the reaction, so the reaction will occur at a different rate.
Are elements able to bond together without enzymes and why?
Enzymes, as used in reactions, usually do not causes bond formation. They are usually responsible for breaking of bonds but when used in bond formation, they are commonly catalysts. Catalysts simply provide a lower activation energy and causes the reaction to occur faster. Thus, without catalysts, the reaction (including bond formation) will still occur, just at a slower rater. Thus, bond formation can definitely occur without enzymes (catalysts).
