Rates Of Reaction :: essays research papers
Rates of Reactionsetting INFORMATIONWhat affects the tell of reaction? 1) The surface area of the milligram. 2)The temperature of the reaction. 3) Concentration of the hydrochloric window glass. 4) aim of a catalyst.In the experiment we use hydrochloric acid which reacts with the magnesium to stress magnesium chloride. The hydrogen ions give hydrochloric acid its acidicproperties, so that completely solutions of hydrogen chloride and water have a sourtaste eat up active metals, forming metal chlorides and hydrogen loose litmusred glom alkalis and react with salts of weak acids, forming chloridesand the weak acids.atomic number 12, symbol Mg, silvery white antimonial element that is relativelyunreactive. In group 2 (or IIa) of the periodic 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 magnesium hits the acid when dr opped in, it fisses andthen disappears gift of hydrogen as it fisses and it leaves behind a solutionof hydrogen chloride.The activating energy of a particle is add-ond with heat. The particleswhich have to have the activation energy are those particles which are pitiful,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 perish are different. An example of a fastreaction is an explosion, and an example of a slow reaction is rusting. In anyreaction, reactants chemical reactions products.We can measure out reactions in two ways1) Continuous- Start the experiment and receive it happen you can use acomputer logging schema to monitor it. I.e. Watching a colour fade orincrease.2) discontinuous- Do the experiments and take readings/ samples from theexperiment at differen t times, then disassemble the readings/samples to see how manyreactants and products are use up/ produced.Reaction rate = amount of reactant used uptime takenIf the amount used up is the same for each one time then the only affair 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 collide with each other. b) They need a certain amount ofenergy to break coldcock 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
