Homework Help: Chemistry

Posted by Tracy on Monday, March 5, 2012 at 10:03pm.

In which direction will the net reaction proceed.
X(g) + Y(g) <==> Z(g) .. Kp = 1.00 at 300k
for each of these sets of initial conditions?
1) [X] = [Y] = [Z] = 1.0 M
a] net reaction goes to the left [this one?]
b] net reaction goes to the right
c] reaction is at equilibrium

b] Px = Pz = 1.0 atm, Py = 0.50 atm
a] net reaction goes to the left
b] net reaction goes to the right
c] reaction is at equilibrium

I chose a because i converted KP to KC for part A.. is this correct so far?: KC = Kp(RT)^-∆n
KC = 1.00[(0.0821)(300k)]^-1 = 0.04060089 < 1.0 M? I don't even know if that approach was right and i honestly have no idea about part B.. please help!
