What is the percentage dissociation of HI at 450°C, if the experiment is started with one mole of HI(g) and 2 moles of N2(g) in the same closed vessel?
Options:
Answer:
C
Solution:
N2 is inert and takes no part in the reaction Here Δn_g = 0, so Kp = Kc = Kx and the position of equilibrium does not depend on total pressure or volume
The mole ratio of HI, H2 and I2 at equilibrium is unchanged by N2
Percentage dissociation stays 25%
This is option (c).
