Answer to Question #204772 in General Chemistry for Master j

Question

Determine the direction the reaction will proceed to counteract these stresses AND establish how the concentration of fluorine (F₂) is expected to change.

ii. 1.5 x 10^-3 mol dm^-3 and 3.0 x 10^-3 mol dm^-3 of hydrogen and fluorine gas, respectively, were present in a closed system at 285 ^oC. At equilibrium, it was found that the concentration of hydrogen fluoride (HF) was 2.8 x 10^-3 mol dm^-3 . Calculate the value of K_c at 285 ^oC.

iii. What physical factor will change the value of K_c for this reaction.

Answer 1

Kc=Na/N*t

Kc=15mol
