Aim: The aim of this experiment is to find out the effect of concentration on the rate of reaction. I will also plan, and carry out an experiment to discover how to change the rate of a reaction Concentration affects the rate of the reaction because the higher the concentration, the faster the reaction. If the solution is made more concentrated, it means there are more particles of reactant knocking about between the water molecules, which make collisions between the important particles more likely. In a gas, increasing the pressure means the molecules are more squashed up together so there are going to be collisions. In any reaction involving solutions, a concentrated solution always reacts faster than a diluted solution. In a more concentrated solution, the particles of the dissolved substance are closer together. This means that when another substance is added, collisions will take place more often. Method: 1. Draw a cross with a dark...
