Question

At a certain temperature, the equilibrium constant for the following reaction is : 4.2x10^-9
H2 + I2 <=> 2HI << al Gases

Use this information to answer following Questions.

1)suppose a 11. L reaction vessel is filled with 1.0 mole of H2 and 1.0 mole of I2 what can you say about the composition of the mixture in the vessel at equilibrium?



2)what is the equilibrium constant for 2HI <=> H2 + I2 << again all gasses


3) what is the equilibrium constant for 2H2 + 2I2 <=> 4HI << al Gasses

Explanation / Answer

1)4.2x10^-9=[HI]^2/([H2][I2]) LET X MOLE OF H2 AND I2 REACT THEN 4.2x10^-9=4X^2/(1-X)^2 X=3.2*10^-5 MOLES MOLES OF HI=2X=6.4x10^-5 MOLES OF H2=I2=1-X=0.999968 2)1/(4.2*10^-9) 2.38*10^8 3)K=[HI]^4/([I2]^2[H2]^2) =4.2^2*10^-18 =1.764*10^-17
