Question

A,B,C,D

Consider the following reaction occurring in a non-rigid container at 25 degree C where K = 1000 H2 (g) + I2 (g) = 2HI (g) delta H degree rxn = -13.2 kJ/mol and delta S degree rxn = 22.0 J/K Based on the information given, which of the following statements is true? Select all that are True. Removal of HI (g) will cause an increase in the value of K. When the temperature is increase, the value of K will increase. Increasing the temperature will cause the reaction to shift to the left For this reaction Kp = Kc

Explanation / Answer

K =[HI]^2/[H2][I2]

hence increase in HI will increase K
....

as enthalpy is negative increase in tepmerature will decrese K

hence reaction will shift to left with increase in temperature

..

as stoichiometric moles of reactants =2= stoichiometric mols of products

hence kp=kc

...

hence ACD is true
