Question
Consider the following reaction 1) If H2 was introduced into the reaction at equilibrium, predict which of the following statements ifcorrect? Cngw d bzt34,0 2 43 If we compare the concentrations of the reactants and products in the final equilibrium mixture ose in the initial reaction mixture, which of the following statements is true? a) [H] 1 will decrease to the amount it was when the system was initially at equilibrium;: [Na] will also decrease and [NHa] will increase stoichiometrically b) [Ha] will decrease, but not back to the amount it was when the system was initially at equilibrium; [N2] will also decrease and [NHa] will increase stoichiometrically c) Since [HI was increased, [N2] will also increase stoichiometrically and IN decreases stoichiometrically 2) When ammonia is synthesized industrially, the gas mixture is pumped through a condenser. The condenser is at a temperature sufficient to liquefy ammonia, but not hydrogen or nitrogen. a) What stress is placed on the system here? b) Since ammonia is removed from the system, how does Q compare to K? c) Which way will the reaction shift to reach equilibrium? d) Which of the following statements correctly describes what happens after the ammonia is removed - INHs] decreases while [H2] and [N2] increase stoichiometrically. [H2] and [N2] decrease in stoichiometric proportions in order to partially replenish some of the lost NHs [H2] and [N2] decrease in stoichiometric proportions in order to fully replenish the lost NH3 to concentrations that existed before it was removed from the reaction mixture. shifts e) So generally when you add a species to a system at equilibrium, the system (towards/ away from) the side with the added species. So generally when you remove a species from a system at equilibrium, the system shifts (towards/away from) the side with the removed species.Explanation / Answer
1) option a is correct on introducing the hydrogen in reaction during equillibrium, the concentration of hydrogen will decrease and also concentration of nitrogen also decrease and concentration of ammonia will increase acc to le chatelier principle reaction moves in forward direction.
2) a - 200 atm pressure is applied on the system
c- equillibrium will shift in forward direction
d- H2 and N2 will decrease stiochiometrically to replenesh the lost of ammonia
e- on adding some species during equillibrium the system will shift away from the side with the species added acc to le chatleir principle
f-the system wiil move towards the side with the removed species
