State of problem The aim of the experiment is to find out the rate of reaction at which Alka-Seltzer tablets react with water. The input variable that I will change is temperature. The output variable will be measured by the time it takes for the Alka-Seltzer tablets to dissolve. Input variables In this experiment there are two main factors that can affect the rate of the reaction. These key factors can change the rate of the reaction by either increasing it or decreasing it. These were considered and controlled so that they did not disrupt the success of the experiment. Temperature- As the temperature increases, the movements of molecules also increase. This is the kinetic theory. When the temperature is increased the particles gain more energy and therefore move around faster. This gives the particles more chance with colliding with other particles and with more force. The increase in temperature will therefore increase...
