Shapes of Molecules

The shape of a molecule determines many of its properties; For example: C4H10 is the formula for 2 separate molecules n-butane and isobutene Melting Point    -138°C                   -159°C Boiling Point     -0.5°C                    -12°C Enzymes—shape compatible with those molecules whose reactions they promote i.e.  the enzyme sucrase breaks down the sugar molecule sucrose The shape of a…

Rate Laws and Order of Reaction

Chemical reactions only take place when there are collisions between reactants Depends on: Number of collisions per unit time Fraction of collisions which are successful There is a relationship/pattern between reaction rate and the factors that affect it This pattern can only be determined empirically (through experimentation) Rate Law Empirical evidence supports that the reaction…
