Document Summary
Rate of forward reactions = rate of reverse reaction. Macroscopic properties constants (looks likes nothing is happening) Must be in a closed system (placing a lid) Macroscopic properties constant (appearance doesn"t change: color, pressure, concentration and ph. Equilibrium can be approached from either side. *equilibrium involves dynamic change at the molecular level but no change at the macroscopic level. More products position of equilibrium lies to the right . If k > 1010 that means reaction is going to completion. More reactants position of equilibrium lies to the left . If k < 10-10 that means reaction is not taking place. Homogeneous equilibrium: reactants and products in same phase. Heterogeneous equilibrium: reactants and products in different phase. Doesn"t necessarily mean that the reaction is at equilibrium. If qc = kc ~ reaction is at equilibrium. At equilibrium, there is a constant ratio between the concentrations of the products and reacts in any change.
