Question

The equation for the decomposition of hydrogen iodide is 2HI-------H2+I2, H=+52kj. Write the equilibrium concentration for the reaction.

Answer 1

Hey, Your Question is little bit wrong. There is no need of the Enthaly as given in the question. From the Enthaly Equilibrium conc. can not be calculated until the temp. or other conditions are not given in the question.

I think, We need to find the Expression for the equilibrium constant expressing the Equilibrium concentration.

The Equilibrium constant is given by,

2HI ⇒ H₂ + I₂

Kc = [H₂][I₂]/[HI]²

Now, In the question there must be given the concentration of the Hydrogen, Iodine and Hydrogen Iodide at the Equilibrium. So by putting this value there, you may fin d the answer.

Hope it helps.
