Lab Report: Reaction Rates The rate of a chemical reaction is the change in the concentration of a reactant or a product per unit. Reactions occur when reactant molecules collide with proper locationing and with the similar energy equal to or greater than the activation energy. Our guiding question was, “What are the factors that affect the rate of reaction?” During the inspection, we first picked out 2 similar zinc pieces and put them into different test tubes. Then, we placed 6 moles of HCL in one test tube with a zinc piece and 3 moles HCL in the other with a zinc piece. Next, we viewed both and noted our observations down in our chart. We managed our investigation this way since of the following instructions we were given. Our claim was, “The factors that affect the rate of reaction are the surface area of solids, the concentration of reactants and temperature and also a catalyst.” The investigation we conducted and provides that we noted all supported this claim. In the first station we saw a solid that was split into smaller pieces with has more surface area than the whole piece with small surface area. The one in smaller pieces had more collision frequency which meant it reacted faster. In our investigations we observed the 6 moles react faster than the 3 moles which told us that the higher concentrations mean higher collision frequency. During the 3rd station, we experienced a sample of any element when we put at a higher temperature will react faster. In conclusion of the experiment, The factors that affect the rate of reaction are the surface area of solids, the concentration of reactants and temperature and also a catalyst. Due to increasing the surface area of a solid reactant exposes more of its particles to increase, more molecules or ions interact to form new compounds, and the rate of reaction increases, disproportionately large increase in the number of high energy collisions and lastly a catalyst
