Rate of chemical Reaction

  The rate of a chemical reaction is the number of moles of reactants converted or products formed per unit time. It varies from one chemical reaction to another because some chemical reactions are faster than others. The rate at which a reaction occurs and its control are significant in industries because they are the factors that determine if the reaction will make economic sense or not. How to measure the rate of chemical reaction Consider a reaction between irons and dilute hydrochloric acid Fe (s) + 2HCl (aq) → FeCl 2(aq) + H 2(g) As the reaction proceeds, the iron is used up and iron (II) chloride and hydrogen gas are formed.   The rate of the chemical reaction between iron and the acid can be determined by: ·          Taking a given mass of iron ·          Adding an excess of hydrochloric acid ·          Noting the time taken for a...
