Investigate A Factor Which Affects the Rate Of Fermentation Of YeastThis experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: Increasing the concentration. (See the lock and key theory.) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. The surface area, the bigger the surface area, the faster the reaction time is, as the reactant can reach more parts. The temperature, an increase in temperature leads to an increase in reactant rate. Generally, as the temperature is increased, the particles get more energy, so they bump into one another more, therefore speeding up the reaction time. This is called the collision theory, which I will discuss in greater depth later. Whether or not there is a catalyst. A catalyst speeds up the rate of reaction and remains chemically unchanged by the end of the experiment. A catalyst lowers the activation energy. This is the energy needed to start a reaction. The variable that I have decided to change is the temperature. I have deci
