Consider the given reaction at equilibrium:
\(\mathrm{N_2(g) +3H_2(g) \rightleftharpoons 2NH_3(g), \Delta H=-Q}\)
Reaction is favoured in forward direction by:
1. Use of catalyst 
2. Decreasing concentration of \(\mathrm{N_2}\)
3. Low pressure, high temperature and high concentration of ammonia
4. High pressure, low temperature and higher concentration of \(\mathrm{H_2}\)

Find the condition that shifts the following exothermic equilibrium towards the formation of NH₃:

N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + heat

1. Increasing the concentration of NH₃
2. Decreasing the pressure
3. Decreasing the concentration of H₂
4. Increasing the pressure and decreasing the temperature
