Equilibrium Reaction Lab

IBDP chemistry IA: Equilibrium reaction clinical test information: reaction based on particle collision, particles must have sufficient energy. If the rate of positive reaction is equal to the reverse reaction rate, the process to achieve equilibrium, some chemical reactions are reversible. Because it seems to be stopping up to speed equal to no change due to cause and overall change. Through this experiment, we will examine the factors that influence the balance of constants.

The equilibrium constant (K) defines the relationship with the concentration of the substance involved in the chemical equilibrium reaction. If stress such as temperature, pressure, or change in concentration in equilibrium reaction stress, the reaction will be transformed to restore balance Principle of Le Chatelier. Because of fever and endothermic reaction, such an increase in stress is a change in temperature. The equilibrium constant at a particular temperature is determined using the ratio of the equilibrium concentrations of the reaction products and is done to indicate the degree of reaction

Two kinds of considerations related to opposite synthesis: position of equilibrium and reaction rate. At room temperature, the equilibrium is strong, which is in favor of ammonia, but the reaction does not proceed at a detectable rate. An obvious solution is to increase the temperature from 1 to about 150 to 200 ° C (302 to 392 ° F), but the reaction is exothermic and is an equilibrium constant (using unit bar or ATM). (In principle refer to Le Chatelier.) According to the Van Hoff equation, at this atmospheric pressure equilibrium state, which exceeds this temperature and immediately becomes very negative. Therefore, low temperature and other methods are assumed to increase the speed. However, the catalyst itself requires a temperature of at least 400 ° C. ] It is effective to C
