Science Coursework Rates Of Reaction

This is basically how hard and how often particles collide with each other.The more and harder they collide, the faster the reaction time will be.If there are greater amount particles then there will be greater number collisions taking place and so the rate of reaction increases as well as the temperature.

Again, I would need approximately six or seven results to create enough points to put on a graph graph.

Collecting Gas using a Syringe Equipment needed: -Scales; -Conical flask; -Gas syringe; -Stand with clamp; -Hydrochloric acid (30 ml); -Magnesium strip (2cm long); -Rubber tube with bung.

I will then measure how long it takes for a chemical reaction to take place.

The time might vary depending on the concentration of Sodium thiosulphate.

The graph will have an independent variable and a dependant variable.

Chemical reactions require collisions, and if particles are moving around more quickly they are obviously more likely to collide. If the people are moving quickly it is more likely that they will bump into each other then if they are moving slowly.It is in this way that particles of solutions react.I will make sure that my experiment is fair by using a different measuring tube and pipette for each chemical. I think that the rate of reaction between sodium thiosulphate and hydrochloric acid will increase as the concentration of the sodium thiosulphate solution increases.I state this because by increasing the concentration you’re also increasing the amount of particles in the solution.This means the higher the temperature, the The last factor that increases rate of reaction is the surface area.Grinding up the magnesium into a powder increases the surface area, so the acid has more space to react on.Using a gas syringe As more gas is produced the plunger inside the syringe moves out of the syringe so the gas can be measured by marks on the syringes length.I would have to measure the amount of hydrogen produced in regular intervals which would change for each concentration.sodium thiosulphate hydrochloric acid sodium chloride water sulphur dioxide sulphur Na2S2O3(aq) 2HCl(aq) 2Na Cl(aq) H2O(l) SO2(aq) S(s) Prediction I predict that the higher the temperature, the more quickly reaction will occur.This is because with heat, the particles of sodium thiosulphate and hydrochloric acid have more energy. It works like this for all substances, not just those two.
