Set up an ICE chart, substitute into Kp expression, and solve.
i did.. it was wrong for the last time
for the last time i did it*
If you post what you did perhaps I can find the error.
I2 = 1.738 atm
2I = 0
I2 = -2x
2I = x
I2 = 1.738 - 2x
2I = x
so i set the equation as
0.254 = x/(1.738 - 2x)
and i solved for x. i got 0.292
and after that how do i get % decomposition?
I^- (not 2I) = 2x
I2 = 1.738-x
Then Kp = pI^-^2/pI2
0.254 = (2x)^2/(1.738-x).
Solve for x. You didn't have 2x and then didn't square it.
%decomposition = (pI^-/1.738)*100 = ??
