Investigation: How does the concentration of acid affect the rate of reaction? :: GCSE Chemistry Coursework Investigation

Investigation How does the submerging of acid affect the stride of reply?The declare oneself of this investigation is to test how concentration affects therate of reaction.My prediction for my investigation is that the high theconcentration, the faster the reaction will be.My reason behind my prediction is The high the concentration, the more(prenominal) particles there are whichwill collide with enough heftiness to overcome activation energy, whichis explained as the collision theory.Collision theory explains how chemic reactions occur and why ratesof reaction differ. For a reaction to occur, particles mustiness collide.If the collision causes a chemical change it is referred to as a high-yield collision. For a reaction to occur, the reactant particlesmust collide. Only a certain separate of the total collisions causechemical change these are called self-made collisions. Thesuccessful collisions have activation energy at the moment of impactto go wrong existing bonds and form new bonds, resulting in the productsof the reaction. Increasing the concentration of the reactants and face lifting the temperature bring about more collisions and therefore moresuccessful collisions, increase the rate of reaction.When a catalyst undergoes collision with the reactant molecules, lessenergy is postulate for the chemical change to take place, and hencemore collisions have capable energy for reaction to occur,therefore the reaction rate increases.The four factors that capture the rate of reaction and therefore the test are1. The temperature. This is because if the concentration is warmer, whence the reaction rate may increase or decrease depending on temperature.2. The Catalyst. This is because if the catalyst is of a larger volume or size than the concentration then it may have an affect on the concentration and experiment that will differentiate results.3. The concentration. This is a variable that will be apply because we are trying to find if t he concentration will affect the rate of reaction.4. The surface area. This is because if the surface areas of the calcium carbonate pieces are different then it will affect the results also because it will give off more gas, the greater the surface area.To achieve the most accurate of results possible I will use allsufficient equipment and data.For my prediction, that the higher the concentration, the faster thereaction rate, I will use pre-test results to help with my evaluationbefore I start my investigation.Before I started my investigation, I did a pre-test experiment thathelped me to piss my prediction.
