That's easy in reactions that produce a gas as one of the products – for example, marble chips (containing calcium carbonate) reacting with hydrochloric acid an acid is a substance that forms a solution with a ph value of less than 7. For choosing a variable, you could change the surface area of the marble chips by using small, medium and large chips (using 1m hcl) the smaller the chips, the bigger the surface area and the faster the reaction. An experiment to investigate the rate of reaction between marble chips and hydrochloric acid analysis from my graph i can see that as the concentration of hydrochloric acid increased as did the rate of reaction this is because when the particles reacted they collided with enough energy to make them react as the concentration of acid increased, the number of particles increased, and so there. Enthalpy 2|page anjelina qureshi mrs gravell rates of reaction coursework chemistry year 11 enthalpy, in chemistry, is the heat content in a chemical reaction the enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. Many chemistry experiments do not involve the use of controls your variables include the volume and concentration of the hcl and the amount of co2 produced in chemistry experiments we keep some variables constant, so that we vary only one constant at a time.
