Would a crushed solid or a large chunk react more quickly with gas?

Would a crushed solid or a large chunk react more quickly with gas?

Crushed solid reacts with gas quickly because the surface area exposed to the gas is much bigger in crushed solid compared to a large chunk. Generally, as particle size decreases, surface area increases, and reaction rate also increases.

Why does a certain mass of iron rust faster when it is broken into small pieces than it does when it is in one piece?

However, if you take the same material and break it into smaller pieces, there is much more surface area exposed that can interact with the other components—allowing the chemical reaction to occur much more quickly.

What makes a reaction occur faster?

Increasing the number of collisions speeds up the reaction rate. The more reactant molecules there are colliding, the faster the reaction will be. In most simple cases, increasing the concentration of the reactants increases the speed of the reaction.

Why do crushed tablets dissolve faster?

The smaller the pieces of the tablet the faster it fizzes because the smaller pieces have more surface area. For the same amount of antacid, the crushed tablet has more surface, or exterior, to react with the water. Since the water can reach more of the tablet immediately, the reaction, or fizzing, happens faster.

Do liquids react faster than solids?

Put simply, the more movement the reactant particles have, the faster they will react. Gases tend to react faster than liquids and liquids react much faster than solids. This all adds up to faster reactions.

Why do gases react faster than liquids?

Gases tend to react faster than solids or liquids: It takes energy to separate particles from each other. When the two the solutions are mixed together, all that is required for a reaction to occur is contact between the lead(II) ions and the iodide ions.

Why does increasing concentration generally increases the rate of a reaction?

For a chemical reaction to occur, there must be a certain number of molecules with energies equal to or greater than the activation energy. With an increase in concentration, the number of molecules with the minimum required energy will increase, and therefore the rate of the reaction will increase.

Why does a powdered solid react faster than a single lump?

A powdered solid will normally produce a faster reaction than if the same mass is present as a single lump. The powdered solid has a greater surface area than the single lump.

What increases the chances of collision between two solids?

Increasing the surface area of the solid increases the chances of collision taking place. Imagine a reaction between magnesium metal and a dilute acid like hydrochloric acid. The reaction involves collision between magnesium atoms and hydrogen ions.

What happens when a gas reacts with a powder?

Imagine a case of a very fine powder reacting with a gas. If the powder was in one big heap, the gas may not be able to penetrate it. That means that its effective surface area is much the same as (or even less than) it would be if it were present in a single lump.

How does the amount of matter in a solid affect reaction rate?

The more finely divided the solid is, the faster the reaction happens. A powdered solid will normallyproduce a faster reaction than if the same mass is present as a single lump. The powdered solid has a greater surface area than the single lump.
