Investigating the effect of Concentration on the rate of reaction between Calcium Carbonate and Hydrochloric Acid Plan Understanding Rate of Reaction In order to fully comprehend what will be happening in my experiment, I must explain what rates of reactions are, and what significance my experiment will have on them. A higher concentration will increase the rate of reaction. This is because there are more particles in the same volume than a weaker concentration, so the particles can collide more frequently, due to being closer together. There is an increased chance of the particles reacting, as more collisions occur. Thus, if calcium carbonate chips were placed into more highly reactive particles of HCl, the rate would increase, due to a large number of HCl particles colliding and reacting with the CaCO3 particles. The reaction rate will tell me how fast or slow my chemical reaction is. As well as concentration being able to affect the...
