Factors Affecting Reaction Rates - CDLI

The surface area of the cube can be increased by dividing the cube into smaller cubes. Surface area is maximized when a single large cube is crushed to fine powder. The rate of reaction of a solid substance is related to its surface area. In a reaction between a solid and an aqueous/liquid/gas species, increasing the surface area of the solid-phase reactant increases the number of collisions ...

Reaction Rates

Now you can increase the concentration of the other solution to produce an increase in the rate of the reaction. How does surface area affect a chemical reaction? If one of the reactants is a solid, the surface area of the solid will affect how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of ...

Particle Size and the Rate of Reaction | Alka-Seltzer®

Place 1 Alka-Seltzer tablet into mortar and grind to a fine powder. Transfer powder into a clear glass. (Note: It's important to have the powder in the cup before adding water.) Add 8 oz./240 mL of water to the glass. Measure and record the time to dissolve. 04 CONCLUSION. Decreasing the size of the particles, which make up a given weight, will increase the number of particles represented by ...

Why does a crushed or powdered compound dissolve …

06/05/2012· A cool way to show the dependence of reaction rate on surface area is by burning powdered metals. Under normal conditions, a chunk of most metals will not burn in air. Take iron, for instance. However, if you turn that chunk into a powder, it has lots of surface area, so the exothermic oxidation reaction can proceed quickly and powerfully. This is the reason that metal powders actually …

Effect on Rate of Reaction of Varying Surface Area (1 ...

The rate of the reaction between calcium carbonate and dilute hydrochloric acid can be judged by measuring the volume of carbon dioxide evolved with time. In this simulation you will discover the effect on the rate of reaction of altering the surface area of a solid reactant, and explain this effect in terms of kinetic particle theory. Task 1: Effect on rate of varying surface area. Simulation ...

Rate of Reaction of Magnesium and Hydrochloric Acid

The aim of this experiment is to verify the effects of surface area of solid reactants and concentration of aqueous reactants on the rates of acid-base chemical reactions. Therefore, we sought to test the duration of reaction of equal lengths Magnesium ribbons with reducing concentrations of hydrochloric acid. Similarly, the duration of reaction will be determined using equivalent weights of ...

The Rates of Chemical Reactions

How does surface area affect a chemical reaction? If one of the reactants is a solid, the surface area of the solid will affect how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of the solid. So the larger the surface area of the solid, the ...

Effect of Particle Size on Reaction Rate - Activity

The rate of chemical reactions that involve solids depends on the particle size of the solid. A finely powdered solid has a larger surface area than an equal mass of a coarsely powdered solid. A larger surface area is a much easier target for colliding molecules. The bigger the target, the easier it is to hit. Fine powders therefore react faster than coarse powders, if all other factors are ...
