To prove this theory, the concentration of 30m L of hydrochloric acid will be altered and its effect on 4g of marble chips will be studied under a constant temperature.When marble chips react with hydrochloric acid, calcium chloride, carbon dioxide and water and produced.

This acid and base reaction is expressed through the chemical equation Ca CO3(s) 2HCl (aq) → Ca Cl2 (aq) CO2 (g) H2O (l).
The collision theory states that when particles of two or more reactants collide, only a certain percentage of the reacting particles have enough energy, also known as activation energy at the moment of impact to break the pre-existing bonds and form a new bond (Mahajan, n.d).
The volume of carbon dioxide produced was measured using a measuring cylinder and a bee hive.
The acid-base reaction taking place in the conical flask produces carbon dioxide as a product which displaces the water in the measuring cylinder.
To prove this theory, this experiment was designed to demonstrate the influence of concentration over reaction rate by measuring the volume of carbon dioxide produced when five different molarities (0.5, 1.0, 1.5, 2.0 and 2.5) of hydrochloric acid measuring 30ml react with 4g of marble chips.
The reliability of the experiment was ensured by repeating the test six times with each molarity of hydrochloric acid.
The volume of carbon dioxide produced is therefore measured by determining the volume of water displaced.
The concentration of the hydrochloric acid was varied throughout the experiment. In this experiment, 4g of marble chips reacted with 30m L of one molarity of hydrochloric acid to prove that concentration has strong correlation with reaction rate.
Due to this unequal sharing, the chlorine atom possesses a slightly negative character and the hydrogen atom a slightly positive character, a condition described by the term polar (The Chemical Bond, 2009).
In this experiment, the two reactants stated above are combined to form a salt, calcium chloride.
