Homework Help: chemistry

Posted by Ben on Monday, October 25, 2010 at 11:03pm.

The question below, i was wondering if it decrease because the N2 is on the right and so to add to left it would be too much so it gets rid of it by decreases and doing to the right? because the left side is (+) endothermic? sorry im a little confused.

if the number was negative would it make a difference?


Consider the following reaction at equilibrium:
2NH3 (g)<-> N2 (g) + 3H2 (g) ΔH = +92.4 kJ
Le Cha^telier's principle predicts that adding N2 (g) to the system at equilibrium will result in
__________.
A) an increase in the value of the equilibrium constant
B) a decrease in the concentration of H2 (g)
C) removal of all of the H2 (g)
D) a lower partial pressure of N2
E) a decrease in the concentration of NH3 (g)
