Given the equation for a system at equilibrium:
N2(g) + 3H2(g) <-> 2NH3(g) + energy

If only the concentration of N2(g) is increased, the concentration of

1. NH3(g) increases
2. NH3(g) remains the same
3. H2(g) increases
4. H2(g) remains the same

Respuesta :

Answer: 1. [tex]NH_3[/tex] increases.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

For the given equation:

[tex]N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)+energy[/tex]

If the concentration of [tex]N_2[/tex] is increased , according to the Le-Chatlier's principle, the reaction has to shift to right or forward direction. In order to do that  the concentration of products has to increase.

Thus the concentration of [tex]NH_3[/tex] increases.
