Slide 3: • For a reaction involving two reactants and two products this can be expressed symbolically as: Slide 4: A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. Slide 5: A reversible reaction is shown by the sign, . a half-arrow to the right (direction of forward reaction), .and a half-arrow to the left (direction of backward reaction) . Slide 6: when steam is passed over red hot iron, magnetic oxide of iron and hydrogen gas are formed. If hydrogen gas is passed over heated magnetic oxide of iron, the reverse reaction takes place, producing iron and steam. IRREVERSIBLE REACTION : IRREVERSIBLE REACTION a reaction whose equilibrium state are shifted so close to either the products or the reactants that the reaction effectively does not have an equilibrium between the products and the reactants. A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction:CaCO3 + 2HCl → CaCl2 + H2O + CO2↑ : A truly irreversible chemical reaction is usually achieved when one of the products exits the reacting system, for example, as does carbon dioxide (volatile) in the reaction:CaCO3 + 2HCl → CaCl2 + H2O + CO2↑ a) Neutralization between strong acid and strong base NaOH + HCl –> NaCl + H2O - when strong acid reacts with hydrochloric acid, it will formed sodium chloride and water. : a) Neutralization between strong acid and strong base NaOH + HCl –> NaCl + H2O - when strong acid reacts with hydrochloric acid, it will formed sodium chloride and water.
