The general form of the equilibrium constant equation is then Keq C c D d A a B b Problems involving chemical equilibria can be placed into a matrix format with two kinds of concentrations identified the initial or non equilibrium concentration Cx and the equilibrium concentration X Note the bracket versus the capital C It is the Section 17 1 Equilibrium State and Equilibrium Constant Chemical reactions do NOT go to completion 100 products even those that look like they do Reactions instead reach a point called equilibrium after which the amount of reactants and products no longer change with time This is because all reactions are
Chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate The Concept of Equilibrium As a system approaches equilibrium both the forward and reverse reactions are occurring At equilibrium the forward and reverse reactions are proceeding at the same rate A System at Equilibrium Equilibrium Worksheet 2 Chemists believe that chemical reactions occur because the molecules involved in the reaction A exist only below a certain maximum temperature B are always unstable C are moving so fast that the chance of interaction is very small D spontaneously break apart then recombine E collide with each
