Concentration Vs Rate Of Reaction Lab
Concentration vs Rate of reaction
Brandon
Introduction
A reaction rate is the speed at which a chemical reaction will occur. Heat, concentration of a chemical, Surface area or a catalyst, will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions.
In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce sulfur, sodium chloride water and sulfur dioxide. The chemical formula for this is: Na2S2O3(aq) + 2HCl(aq) → S(s) + SO2(g) + 2NaCl(aq) + H20
Sodium thiosulphate + hydrochloric acid → sulphur + sulfur dioxide + sodium chloride + water
Purpose …show more content…
The experiment will show if a higher or lower concentration will increase or decrease time of reaction.
Hypothesis
I believe that having a higher concentration of sodium thiosulphate will cause the reactant to react faster. This is because the higher the concentration chemical,the more molecules present causing the elements to have a higher chance of productive collision.
Variables
Independent Variables
Dependant Variables
Concentration of a substance is a independent variable because we use it to change how fast the atoms combine.
The time it takes for the sulfur precipitate to form. This will be changed when using different independent values.
Temperature is the independent variable because we have a set temperature.
Rate of reaction is dependant on all the independent variables because each one of them change the value of the time therefore changing the rate of reaction.
Surface area is another independent variable because it will set how fast the elements will combine.
Catalyst is a independent variable because it will change the rate of
