A decrease in pressure results in the rate of reaction slowing down due to particles is further apart and kinetic energy is lost so they slow down and collides with less force. Concentration. In this experiment the concentration can be altered in various ways...

Increasing the strength of the acid, making it stronger or weaker by adding more parts of acid per water. Also I can increase the amount of the hydrochloric acid I put in, 10ml to 20ml doing this increases the chances of molecules colliding due to there is more chance of a collision, however As a reaction proceeds, the concentration of the reactants usually decreases as they are used up...

preliminary results Sodium + Hydrochloric Sulphur + Sulphur + Water + Sodium Thiosulphate acid Dioxide Chloride Na2S2O3 + 2HCl S + SO2 + H2O + 2NaCl As you can see from the word equation there are a lot of bonds to break in this experiment so the more "HCl's" there are the quicker it will be to break the Sodium Thiosulphate...	2 / 364
GCSE Chemistry PLANNING Background Information: During a chemical reaction the reacting particles must collide with each other, however, collision alone does not guarantee that the reaction will start...	1 / 246
Rates of Reaction Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate...	4 / 915
Rate of Reaction Chemicals Aim My aim for this experiment is to find the rate of reaction of the following chemicals shown below in the equation furthermore I will use different concentrations of Hydrochloric acid...	3 / 599
Chemistry Rates of Reaction Coursework: Sodium thiosulphate and hydrochloric acid Simple Procedure Place a conical flask on a piece of paper with a cross on it. Add hydrochloric acid and sodium thiosulphate, and record the amount of time taken for the cross to disappear through the solution from the top of the flask...	4 / 986
What Effect The Concentration Of Acid Has On The Rate Of Reaction Aim The aim of this experiment is to find out what effect concentration has on a rate of reaction. Prediction I predict that the higher the concentration of the acid, the faster the reaction will take place, this is because when there is a higher concentration, to a certain extent, there is more particles, so the higher the concentration of acid, the more particles there would be, so these particles will have more chance of colliding with each other, which is what causes the reaction...	2 / 515
Rate Of reaction I am going to investigate how the concentration of an acid affects the rate of reaction. The rate or speed of a chemical reaction is a measure of how fast the reaction takes place...	5 / 1346
