Question 6 Le Chatelier's Principle states that: O a disturbing force must be applied to a system in order for it to reach equilibrium. o when a system at equilibrium is disturbed, a new equilibrium constant is established. O when a chemical system at equilibrium is disturbed, the system shifts in order to minimize the effect. when a chemical system is at equilibrium it is no longer possible to alter the system.

Question 4 1 pts Le Chatelier's principle states that: Only exothermic reactions can reach chemical equilibrium. Only reactions in which a catalyst is present can reach chemical equilibrium. If a chemical equilibrium is disturbed, the system will try and reestablish equilibrium. If a chemical equilibrium is disturbed, the temperature of the system will always decrease.

Select all of the following that are true about disturbing an equilibrium (Le Chatelier's principle). When an equilibrium is disturbed by adding an additional amount of one of the reactants, the system will response by making more products. When an equilibrium reaction is disturbed by adding more of one of the products, it will shift toward the reactants to return to equilibrium. All of the concentrations will change, but it will return to the same original value of Keg....

Laboratory 11, Equilibrium Control of a Reaction Name Chemical Equilibrlum: equilibrium is when the rates of the forward and reverse reactions are equal. Therefore, the concentration of all reactants and products remain constant. This is not to say that the reaction has ceased. It is a dynamic situation at chemical equilibrium with the rate of disappearance of reactants the same as the rate of appearance of reactants through the reverse reaction (the same for the rate of disappearance and appearance...
