Question
Consider the following reaction at equilibrium: 2NH3 (g) ? N2 (g) + 3H2 (g) ? H° = +92.4 kJ Le Châtelier's principle predicts that removing N2 (g) to the system at equilibrium will result in ________. Consider the following reaction at equilibrium: 2NH3 (g) N2 (g) + 3H2 (g) H° = +92.4 kJ Le Châtelier's principle predicts that removing N2 (g) to the system at equilibrium will result in ________.
a. a decrease in the concentration of NH3
b. removal of all of the H2 a lower partial pressure of H2
c. an increase in the value of the equilibrium constant
d. an increase in the concentration of NH3
Explanation / Answer
reaction : 2NH3 (g) --------------> N2 (g) + 3H2 (g) H° = +92.4 kJ
removing N2 , then the concentration of products decreases. so according to Le Châtelier's principle equilibrium will shift to less concentration side. so reaction shift to right side.
decrease the concentration of NH3.
Answer : a) a decrease in the concentration of NH3
