The formula for this reaction is: The speed at which the reactants will create the products is called the rate of reaction. This follows a theory called the kinetic theory. In solids the particles are positioned close together which allows them to vibrate slightly.

Rates of Reaction: Hydrochloric Acid + Calcium Carbonate Essay Sample

Between them are strong bonds that hold them together in a fixed place. The particles present in liquid have further distance between them; therefore the forces of attraction are less than in solids. The particles have weaker bonds that allow them to move.

The particles in a gas are much further apart than in a solid or liquid, and have very weak bonds that allow them to move quite freely. There are virtually nil forces of attraction between the gas particles. This therefore means that solids would have the slowest rate of reactivity, liquids would me in the middle, and gasses would have the fastest rates of reaction.

The factors that would affect the rate of reaction would be: Concentration of hydrochloric acid. The higher the concentration of the acid the faster the rate of reaction will be. This is because there would be more particles of hydrochloric acid present in the reaction; therefore there would be more collisions, which would therefore results in a faster rate of reaction.

The following diagram can show this overleaf: As you can see, in the low concentration of hydrochloric acid, there are 5 particles present, compared to 8 particles of calcium carbonate. In the higher concentration however, there are 10 particles of hydrochloric acid present, and the same amount of calcium carbonate particles present.

This should therefore double the rate at which carbon dioxide is produced as there is now double the amount of collisions occurring. Catalyst catalysts are useful in a reaction as it speeds up the rate of reaction without being used up. Most catalysts are there to speed up the rate of reaction, however some can slow them down.

The ones that speed up the rate of reaction are called activators, and those that slow down the rate of reaction are called inhibitors. For example, in the reaction where the enzyme biological catalyst breaks down hydrogen peroxide H2O2 into water H2O2 and oxygen O2glycerine is sometimes added, this is in order to slow down the rate at which hydrogen peroxide is broken down during storage.

Most of the catalysts that are used are transition metals and their compounds, such as the making of margarine, where a nickel catalyst is used. The nickel catalyses an addition reaction, between a double bonded hydrocarbon alkenesthe oil, and hydrogen.

The result is a solid fatty product, which is margarine. By controlling the rate of reaction i. A catalyst allows a substance to react more easily by reducing the activation energy.CaCO3 +2HCL Co2 +CaCl2 +H2O CalciumHydrochloricCarbonCalciumWater CarbonateAcidDioxideChloride Prediction I predict that when the small marble chips are added to the hydrochloric acid the rate of reaction will be faster and therefore will result in .

When calcium carbonate is added to hydrochloric acid a reaction takes place. The solution fizzes and gives off the gas carbon dioxide/5(1).

How Can We Speed up the Reaction Between Calcium Carbonate and Hydrochloric Acid? - Lab Report

Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas.

One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction. Marble is calcium carbonate and thus behaves in the same way: CaCO3 (s) + 2HCL (aq) &#; CaCL2 (aq) + H2O (l) +CO2 (g) In this experiment, I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction.

Rates of Reaction: Hydrochloric Acid + Calcium Carbonate Essay Sample Background Information: Hydrochloric acid is a clear, colourless, highly-pungent solution of hydrogen chloride (HCl) in water.

It is a highly corrosive, strong mineral acid with many industrial uses.
