1. Is there a reversible reaction for the aqueous solution of cobalt chloride? 2. Write the equation for the reaction of aqueous cobalt chloride. If the reaction is irreversible, use the single arrow (→) to show the direction of the reaction. If the reaction is reversible, use the double arrow (⇒) to show reversibility. 3.

When the reversible reaction N_2 (g) + O_2 (g) 2 NO_(g) has reached a state of equilibrium (A) no further reaction occurs (B) the total moles of products must system the remaining moles of reactant. (C) the concentration of each substance in the system will be constant. (D) the addition of a catalyst will cause formation of more NO. tetrafluoride,

Question: Consider the reversible reaction. PCl5↽−−⇀PCl3+Cl2 1.What substances are present at equilibrium? a. PCl5 b. PCl3 c. Cl2 2. Are the concentrations of phosphorus pentachloride, PCl5, and phosphosphorus trichloride, PCl3, constant or changing at equilibrium? a.

2. Lechâtelier's Principle states that if a stress is applied to a reversible reaction at equilibrium, the reaction will undergo a shift in order to re-establish its equilibrium. Consider the following exothermic reversible reaction at equilibrium: 2AB+C In which direction (left or right) would the following stresses cause the system to shift? a.

What is meant by reversible reaction? A reaction that has reached equilibrium A reaction that will never achieve equibilibrium A reversible reaction is one in which a forward reaction and a backward reaction happen simultaneously A reversible reaction is one in which a forward reaction and a backward reaction do not happen simultaneously A reaction that goes only in one directio

A reversible reaction that occurs in a single step has ΔH = -19.2 kJ/mol and E a = 24.7 kJ/mol. What is the activation energy of the reverse reaction There are 2 steps to solve this one.

The first-order, reversible reaction A ⇄B + 2C is taking place in a membrane reactor. Pure A enters the reactor, and B diffuses through the membrane. Unfortunately, some of the reactant A also diffuses through the membrane. You willassume that the reaction follows elementary rate law and that it takes place isothermally and isobarically.

Question: Consider the reversible reaction A⇌B. If k1 (the rate constant for the forwardreaction A→B ) is 0.05s-1, and if k2 (the rate constant for the reverse reaction B→A) is 0.25s-1, then which of the following represents the fraction of molecules thatare A (i.e., the reactant) at equilibrium?

6. Consider the following general reversible reaction is taking place in a reaction vessel and achieved a state of chemical equilibrium. A + 2B 2x If stress is applied to this reaction at the stage of chemical equilibrium then in which direction (forward or backward) the equilibrium will shift. a. Increase in concentration of A b.

When the reversible reaction, N2 + 02 #2 NO, has reached a state of dynamic equilibrium, which statement(s) below islare) true? I. Both the forward and reverse reactions shut down and no more NO, N2 or O2 are produced. The rate of the forward …
