8.5.3<Tab/> v<Tab/>Fractional distillation of petroleum is performed to obtain products which are useful for use as solvents, polymer products, road-making materials, lubricants and pharmaceuticals. Products from fractional distillation of petroleum are petrol, kerosene and diesel. The separation of petroleum into its 'fractions' depends on differences in the boiling points of the mixture's various components. If the components have similar boiling points, the separation cannot be …

…be used as a catalyst in a reaction between hydrogen and nitrogen in the production of ammonia. Iron speeds up the reaction without affecting the products. v<Tab/>Catalysts increase the rates of reactions by acting as an additional reactant which has a smaller activation energy. In reacting with the reactants and effectively lowering the activation energy, catalysts provide additional energy to the reaction, thus increasing the rate of chemical reaction.
