Where is the direction of equilibrium upon removal of NH3 in the reaction below: N2(g) + 3H2(g) = 2NH3(g) Equilibrium will remain the same. Equilibrium will shift to the right producing more NH3. Equilibrium will increase in favor of the products. Equilibrium will shift to the left, producing more N2 and H2.

. For the reaction system C(s)+H2O(g)H2(g)+CO(g)which has already reached a state of equilibrium, predict the effect that each of the following changes will have on the position of the equilibrium. Tell whether the equilibrium will shift to the right, will shift to the left, or will not be affected. a.

Carbon monoxide gas is removed as it forms by use of a chemical absorbent or “scrubber.” c. An additional amount of solid carbon is added to the reaction vessel.
. Explain what it means that a reaction has reached a state of chemical equilibrium. Explain why equilibrium is a dynamic state: Does a reaction really “stop” when the system reaches a state of equilibrium? Explain why, once a chemical system has reached equilibrium, the concentrations of all reactants remain constant with time. Why does this constancy of concentration not contradict our picture of equilibrium as being dynamic? What happens to the rates of the forward and reverse reactions as a system proceeds to equilibrium from a starting point where only reactants are present?

What happens to the value of the equilibrium constant with this change?

Based on your answers to parts (a) and (b), which is more important in determining the position of this equilibrium, the entropy effect or the energy effect? In which direction will the equilibrium shift as the temperature increases above 200. °C? Explain. Suppose that the pressure were increased to triple its initial value. In which direction would the equilibrium shift? Why is the equilibrium not established at room temperature?
