why does grinding a solid into a powder increase reaction rate

The Rates of Chemical Reactions The Rates of Chemical Reactions

Energy, which is the capacity to do work or produce heat, affects the rate at which a solute will dissolve. Breaking up, crushing or grinding a sugar cube before adding it to water increases the sugar's surface area. The more surface area a solute has, the faster it will dissolve because more particles of the sugar can interact with the water.

You can increase the surface area of a solid by breaking it down into smaller pieces (see also nanoparticles). A solid that is broken down into a powder has the largest surface area and therefore has the fastest reaction rate. This is why a catalyst is often used in the form of a powder.

 · Definition of Reaction Rate. The Reaction Rate for a given chemical reaction is the measure of the change in concentration of the reactants or the change in concentration of the products per unit time. The speed of a chemical reaction may be defined as the change in concentration of a substance divided by the time interval during which this change is observed:

Hence, the rate of a reaction between two phases depends to a great extent on the surface contact between them. A finely divided solid has more surface area available for reaction than does one large piece of the same substance. Thus a liquid will react more rapidly with a finely divided solid than with a large piece of the same solid.

 · If we take that glowing splint and insert it into pure oxygen gas, the reaction will increase its rate by a factor of five - since pure oxygen has 5 times the concentration of oxygen than is in air. When the reaction occurring on the glowing splint increases its rate by a factor of five, the glowing splint will suddenly burst back into full flame.

Yeast operates best in a range of 75 to 85 degrees Fahrenheit. For each degree that you increase the temperature within that range, you will increase the fermentation rate by three to five percent. A 10-degree rise in temperature within this range can achieve a 30 percent to 50 percent increase in the rate.
