The following reaction is brought to equilibrium at 700 °C.

Indicate whether each of the following statements is true, false, or not possible to evaluate from the information given.

(a) If the equilibrium mixture is allowed to expand into an evacuated larger container, the mole fraction of H₂ will increase.

(b) If several moles of Ar(g) are forced into the reaction container, the amounts of H₂S and CH₄ will increase.

(c) If the equilibrium mixture is cooled to 100 °C, the mole fractions of the four gases will likely change.

(d) If the equilibrium mixture is forced into a slightly smaller container, the partial pressures of the four gases will all increase.
