Rate of Reaction Investigation 2HCL + NASO + 2NaCL Hydrochloric acid + Sodium thiosulphate entropy + Sodium chloride + S0 + H0 + Sulphur dioxide + Water Collision Theory For this experiment we can use the hit theory. Collision theory explains how chemical replys occur and why rates of answer differ. When particles collide, they may react. A reaction occurs when particle is facing in the counterbalance direction and the collision has enough energy. If more(prenominal) collisions occur, then the chance of a successful collision is higher. IMAGE Aim To investigate the rate of reaction amidst hydrochloric acid and sodium thiosulphate using variables. Equipment Sodium Thiosulphates Hydrochloric Acid Title tag with a cross - Then we will know when the reaction has interpreted come forth. Measuring cylinder - Measure how much of solution you use from each one time, so its a fair test. Beaker - Where the reaction will take place B unsen burner - How the temperature can increase. Tripod - To place the beaker onto. Stopwatch - Measuring how long the reaction takes place. Thermometer - To measure how hot the mixture is. Factors/ Variables Catalyst - A catalyst is a substance which increases the speed of a reaction without being changed or apply up in a reaction. The catalysis works by large-minded the reacting particles something to stick to where they can collide into each other this increases the number of collisions. submersion - If the solution is made more concentrated it means there atomic number 18 more particles of reactant between the important particles are more likely. Temperature - When the temperature is increased the particles whole move quicker, if they are moving quicker, they are going to have more collisions. We used a thermometer to control this. Particle size/ surface field of study - As the particle size decreases the surface area increases. The rate o f reaction will increase because the acid can attack from different places.
