Question

Equal concentration of Hydrogen and Iodine are mixed together in a closed containar
at 700 K & allow to come to equiibrium. If the concentration of HI at equilibrium is
0.85 mol/dm3
. What are the equilibrium concentrntions of H2
& I2
, If KC
= 54 at same
temperature.

Answer 1

Answer:

The equilibrium constant for the reaction, H2 + I2 2HI at 700 K is 56. If 0.5 mole of hydrogen and 1 mole of iodine are added to the system at equilibrium, ...

H2 + I2 ⟶ 2HI At t = 0 : - a a 0 At equilibrium: - (a - x) (a - x) 2xEquilibrium constant(k) = 2x^2(a - x)^2 56 = 4x^2a^2-2x+x^2 56a^2 - 112x + 56x^2 ...
