Given the equation representing a system at equilibrium:
N2(g) + 3H2(g)<==>2NH3(g) + energyWhich changes occur when the temperature of this system is decreased?
(1) The concentration of H2(g) increases and the concentration of N2(g) increases.
(2) The concentration of H2(g) decreases and the concentration of N2(g) increases.
(3) The concentration of H2(g) decreases and the concentration of NH3(g) decreases.
(4) The concentration of H2(g) decreases and the concentration of NH3(g) increases.

If we added heat to the system, it would push to produce more and more NH3(g) and energy. However, the problem says the temp of this system is decreased, which means they react to produce more and more N2(g) and H2(g). Therefore, the concentration of H2(g) and the concentration of N2(g) both increase, and statement (1) is correct.
Hope this would help :))
