Hard Equilibrium chemistry question!

[From: ] [author: ] [Date: 11-09-11] [Hit: ]
And an extra thankyou to those who can help!Qc = 1^2 / ( 2*1^3)= 0.5Q = K no reaction.No reaction concentrations are at equilibrium conditions.......
Hey guys PLEASE help me out with my Year 12 chemistry work! Here is the question that I don't understand:

2.0 mol N2, 1.0 mol NH3, 1.0 mol H2 are heated in a 1.0L flask at 400 degrees celcius
for the reaction N2(g) + 3H2(g) <---> 2NH3, Kc = 0.50 at 400 degrees celcius

Will a net reaction occur? If so, in which direction?


Thankyou sooo much in advance if you have taken the time to even read this! And an extra thankyou to those who can help!
It's really appreciated :)

Kc = [NH3]^2 / ([N2][H2]^3)

Qc = 1^2 / ( 2*1^3) = 0.5 Q = K no reaction.

No reaction concentrations are at equilibrium conditions.
