Science Coursework Investigating the effect of temperature and surface area on the reaction between sodium bicarbonate tablets and hydrochloric acid ???? ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? Prediction In the experiment I predict that the higher the temperature the faster the reaction time will be and that the larger the surface area the faster the reaction time. This is because of collision theory. Particles only react when they collide with enough energy for the reaction to take place. when you heat them you are giving them energy and so they move faster and therefore collide more often and with greater energy. More successful collisions per second means a faster rate of reaction. Using a powder instead of a lump means the surface area is greater, which means a greater area of reactant is exposed and so available for a collision. Hypothesis There are two different variables that i shall change in the experiment. The first one is the surface areas of...
