Rate of Reaction Between Marble Chips and Hydrochloric Acid To investigate the factors which affect the rate of reaction between marble chips and hydrochloric acid, with one in specific detail. Scientific knowledge: Marble chips erode when they are exposed to acid rain or pollution. Erosion is evident when you look at older marble buildings as in certain cases the erosion take a long time. It is more likely to occur in areas, where there is more pollution. This is because there are a greater number of industries in city than in the countryside. Especially the higher amount of cars which release carbon dioxide, formed as a waste gas in reactions such as internal combustion. Carbonic acid (the product of carbon dioxide…show more content…
If each collision requires less energy, then more collisions can take place in a shorter period of time. They also provide a surface for the molecule to attach to, increasing the probability of particles bumping into each other. However, each different reaction needs a unique catalyst. Surface of a catalyst Temperatures: Increasing the temperature gives the particles more energy, resulting in faster moving particles and, consequently, more collisions and an increased rate of reaction. When the reactants are heated, the rate generally increases. When the reactants are cooled, the reaction generally goes slower. According to the collision theory, particles must collide in order to react. Heat gives the particles more energy to move around and so they increase their speed. This increases the chances of a collision, and more importantly a successful one, as they are hitting each other with greater force with increased energy. On the other hand, cooling has the opposite effects and the chances of successful collisions are reduced. Cold Hot Surface Area: A smaller piece within a large surface area means more areas of contact, resulting in an increased number of collisions and, so, an increased reaction rate. When the surface area of the solid reactant is increased, i.e. the reactant is powdered, the rate of the reaction will also increase. This is because there are more particles exposed for the particles of the other reactant,
