Chemistry Coursework An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid Planning Section When dilute hydrochloric acid reacts with marble chips the following reactions occurs: CaCO3 + 2HCL = H2O + CO2 This is the reaction we will be investigating. We will be investigating what changes the rate of reaction. A list of variables that could affect the rate of reaction ? Temperature ? Concentration ? Surface Area ? Temperature: This variable changes the rate of reaction, when the temperature is increased the rate of reaction is quicker, because the particles have more energy to move around and collide with each other. The more collisions between particles in a given time, the faster the rate of reaction. ? Concentration: There will be a concentration of acid and a concentration of water as well. This variable changes the rate of reaction, by adding more acid in concentration than the water...
