Sara Rider Rates of Reaction. Introduction: During the reaction between sodium thiosulphate and hydrochloric acid I know that a solid sulphur will be formed and also that the solution of the two will turn cloudy before going completely opaque, also during this a poisonous gas is also given off called sulphur dioxide. For the reaction to take place I know that the particles of these two reactants must make successful collisions and that if during the reaction more particles collide successfully then the reaction will go faster, but if reacted alongside water then the reaction will be diluted slightly the rates of reaction will be lowered. From this first evidence I can make an primary prediction that doubling the concentration of the chemicals will double the rate of reaction. I predict this because if there is double the concentration then there will be double as many particles meaning that there will...
