Explanation: as pressure is increased, equlilibrium shifts towards the side with less moles of gas.
Balanced equation :

hope this helps!
Answer:
0.89 moles of N2 gas
Explanation:
From Avogadro's law:
V1/n1 = V2/n2
n2 = V2n1/V1
V1=11.2L
V2= 20L
n1=0.5 moles
n2 = ??
Therefore
n2= 20×0.5/11.2= 0.89 moles
