Rates Of Reaction :: essays research papers
Rates of responseBACKGROUND INFORMATIONWhat affects the tramp of reaction? 1) The surface argona of the atomic number 12. 2)The temperature of the reaction. 3) closeness of the hydrochloric acid. 4)Presence of a catalyst.In the look into we use hydrochloric acid which reacts with the milligram toform magnesium chloride. The atomic number 1 ions give hydrochloric acid its acidicproperties, so that solely solutions of hydrogen chloride and water wee-wee a sour gustation corrode active metals, forming metal chlorides and hydrogen turn litmus ruby-red neutralise alkalis and react with salts of weak acids, forming chloridesand the weak acids.Magnesium, symbol Mg, silvery exsanguinous metallic element that is relativelyunreactive. In group 2 (or IIa) of the oscillating table, magnesium is one of thealkaline earth metals. The atomic number of magnesium is 12.Magnesium(s) + Hydrochloric acid(aq) = Magnesium Chloride(aq) + Hydrogen(g)Mg + 2HCl= MgCl2+ H2In the reaction when the ma gnesium hits the acid when dropped in, it fisses and and so disappears giving of hydrogen as it fisses and it leaves behind a solutionof hydrogen chloride.The activation energy of a particle is increased with heat. The particleswhich have to have the activation energy are those particles which are moving,in the case of magnesium and hydrochloric acid, it is the hydrochloric acidparticles which have to have the activation energy because they are the onesthat are moving and bombarding the magnesium particles to produce magnesiumchloride.The rate at which all reactions happen are different. An illustration of a fastreaction is an explosion, and an example of a slow reaction is rusting. In anyreaction, reactants chemical reactions products.We tail measure reactions in two ways1) Continuous- Start the experiment and watch it happen you can use acomputer record system to monitor it. I.e. Watching a colour fade orincrease.2) Discontinuous- Do the experiments and take readings/ samples f rom theexperiment at different times, because analyse the readings/samples to see how manyreactants and products are used up/ produced. response rate = meat of reactant used uptime takenIf the amount used up is the same each time then the wholly thing that changes isthe time taken.so, reaction rate 1time taken.rate = Ktime taken.Where K is the constant for the reaction.For particles to react-a) They have to jolt with each other. b) They need a certain amount ofenergy to exhibit down the bonds of the particles and form new ones. This energyis called the Activation Energy or Ea.When we increase the temperature we give the particles more energy which1) Makes them move faster which In turn makes them collide with each other more
