Rate of Reaction 0.0 / 5 ? ChemistryRate of reactionGCSEAQA Created by: HarryCreated on: 19-04-14 09:44 What experiment investigates the effect of concentration on rate of reaction? Acid & Sodium Thiosulphate solution on paper with a cross 1 of 8 What is the formula to discover the rate of reaction? Rate = 1 divided by :time: x 1000 2 of 8 What is an independent variable? A variable you change in the experiment 3 of 8 What is a dependent variable? The variable you measure of the independent variable 4 of 8 What can you conclude about concentration on rate of reaction? As concentration increases, the rate of reaction increases 5 of 8 How can you explain the conc. x rate of reaction? Concentrated => aka. more particles, therefore: more particles result with more successful collisions, resulting with a faster reaction 6 of 8 What are control variables? Every other variable in the experiment, need to stay constant. 7 of 8 What experiment investigates the effect of catalysts on rate of reaction? Side arm tube, Hydrogen Peroxide & catalyst, trough with burette that collects Oxygen 8 of 8
