Experimental Report Of Facrtors Influencing The Rate Of A Chemical Reaction.
Factors Influencing Rate of Reaction
Aim
To investigate several effects believed to influence rate of reaction, concentration of a substance and temperature, and observe the effects.
Hypothesis
Concentration and temperature will both increase the rate of reaction in accordance with collision theory.
Introduction
The reaction rate or rate of reaction for a reactant or product in any given reaction can be defined as the speed with which a reaction occurs. For example, the oxidation of iron (rusting) is a slow reaction which can take many years, but explosive combustion, such as the ignition of fuel, can take as little as fractions of a second to complete.
Dealing closely with reaction rates is collision theory. First proposed in 1916, collision theory describes qualitatively how and why chemical reactions occur, and how the rate of reactions differs from reaction to reaction. It theorises that, for a reaction to occur, the reactant particles must collide, but only a......
