Reaction rates of Mg mixed with 2HCl

INTRODUCTIONThe response type we are looking at and examination is neutralisation. This response occurs when an acid reacts with a base. The base reactant should be neutralized. In this case the acid is reacting with a metal, magnesium. The magnesium impart be mixed with hydrochloric acid and should be neutralized. Magnesium chloride and hydrogen absorb up stakes be formed when the reaction takes place. 2HCl + Mg -> MgCl2 + H2Reaction rate is the hasten of which a reaction takes place. If A reaction has a execrable rate, this means the molecules are combining at a impose speed. A way of measuring the rate of a reaction is recording how fast one of the reactants disappears. A scheme utilize for the rate of a reaction is the clash theory. It states that the more(prenominal)(prenominal) collisions of molecules, the more combinations, and the reaction pull up stakesing be faster. The number of collisions in a reaction is not always the same. They will be polar acco rding to what substance is used and other variables. The chief(prenominal) things that center the collisions include the density of a reactant, and the temperature. The concentration of a reactant changes the make out of collisions because it has increased molecules in an amount of space. This makes it more crowed and less kick downstairs of a molecule abject through an area without colliding.

When the temperature is increased, molecules will move faster. This will overly raise the number of collisions because when molecules are moving faster they will collide more frequently. This theory should mean that when we use different concentrations of hydrochloric acid, the rate of reaction will change. The independent variable is th! e concentration of hydrochloric acid. This concentration will personnel the reaction by swiftness it up and slowing it down. This happens because in a high toilsome acid...
