question 24

Multiple Choice

Consider the following reaction: 2HF(g) H₂(g) + F₂(g) (K = 1.00  10^-2)
Given 1.22 mol of HF(g) , 0.760 mol of H₂(g) , and 1.09 mol of F₂(g) are mixed in a 4.00-L flask, determine the reaction quotient, Q, and the net direction to achieve equilibrium.

• A) Q = 0.557; the equilibrium shifts to the right.
• B) Q = 0.679; the equilibrium shifts to the left.
• C) Q = 0.679; the equilibrium shifts to the right.
• D) Q = 0.557; the equilibrium shifts to the left.
• E) Q = 1.43; the system is at equilibrium.
