Chapter 17, Problem 126CP

. Consider the following exothermic reaction at equilibrium:
${\text{N}}_2\left(g\right)+{\text{3H}}_2\left(g\right)\rightleftharpoons {\text{2NH}}_{\text{3}}\left(g\right)$   Predict how the following changes affect the number of moles of each component of the system after equilibrium is re-established by completing the table. Complete the table with the terms increase, decrease, or no change.

	N2	H2	NH3
Add N2(g)
Remove H2(g)
Add NH3(g)
Add Ne(g)
(constant V)
Increase the
