The K_c for the Formation of HI from Iodine and Hydrogen

question 7

Multiple Choice

The K_c for the formation of HI from iodine and hydrogen gas is 54. If the concentrations of HI, I₂, and H₂ are 0.338 M, 0.112 M, and 0.198 M respectively, which statement is correct?

• A) Q = 5.15 which is less than K_c, therefore the reaction needs to proceed towards the right to reach equilibrium
• B) Q = 15.2 which is less than K_c, therefore the reaction needs to proceed towards the right to reach equilibrium
• C) Q = 0.194 which is less than K_c, therefore the reaction needs to proceed towards the right to reach equilibrium
