Unit 11: Kinetics and Equilibrium Activated complex: an intermediate state that is formed during the conversion of reactants into products‚ the structure that results at the maximum energy point along the reaction path. Activation energy: a chemical reaction is the difference between the energy of the activated complex and the energy of the reactants. Catalyst: substance that increases the rate of a chemical reaction by reducing the activation energy‚ but which is left unchanged by the reaction

CONDITION OF EQUILIBRIUM IBAÑEZ‚ Jonen Lery L. OBJECTIVE A torque is an influence‚ which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm. In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the systems of equilibrium and the

of this experiment are to be able to define equilibrium‚ equilibrium position‚ equilibrium constant‚ reaction quotient and Le Chatelier’s Principle. Another objective is to explain how changes in temperature‚ pressure and concentration affect the equilibrium position of a reaction. Also‚ perform chemical equilibrium reactions and manipulate equilibrium positions through concentration and temperature and perform calculations to determine the equilibrium constant (K) and the reaction quotient (Q) of
