After the student pushes on the wall, the student moves to the right. Based upon the forces you selected as present
above, which explanation best explains the motion of the student.
A. The motion of the student is best explained by Newton's Third Law. As the student pushes on the wall, the wall
pushes back on the student. Because the force from gravity is balanced by the force of the floor, the only force
present on the skateboard and the student is the force applied by the wall on the student.
B. The motion of the student is best explained by Newton's First Law. The student is at rest until a force is applied
against the wall. The push of the student against the wall is directly responsible for the motion of the student.
C. The motion of the student is best explained by Newton's Second Law. The wall does not move when the student
pushes on it; however, the student does move due to the relatively small mass of the student.

Explanation:
a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional ammonia will be produced .
b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.
c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³
d ) Substituting the given values in the equation ,
Keq = [ 6M ] ² / [ 3M] [ 4M]³
= 36 / 3 x 64 M⁻²
= 18.75 x 10⁻² M⁻² .
