For this assignment‚ you will be designing a lab to investigate factors that affect the rate of a reaction. You are not required to conduct the experiment‚ but it may be beneficial to do so if you can acquire the materials needed for your design. The reaction that you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is

Reaction Rate Coursework Aim To see how the concentration of a reactant affects the rate of reaction‚ in this case sodium thiosulphate and acid. Scientific Background For a reaction to occur‚ the particles of the reactants must be colliding with each other with enough energy‚ the amount of energy needed for the reaction is called activation energy. Activation energy is altered by temperature‚ concentration‚ surface area of and the pressure on the reactants. Stirring the reactants also increases

In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray
