question 2

Multiple Choice

Consider the Haber process for preparing ammonia from nitrogen and hydrogen as shown below and the reaction s corresponding equilibrium constant at 532 C.
N₂(g) + 3 H₂ (g) 2 NH₃(g) K eq (532 C) = 0.19
At a particular moment, the following equilibrium concentrations were observed:
N₂= 0.079 M, H₂ = 0.12 M and NH₃= 0.0051 M. After calculating the reaction quotient , Q , what can be stated about the direction in which this reaction is proceeding?

• A) Not enough information is provided to make an assessment.
• B) This reaction is proceeding left to right as written. (reactants to products)
• C) This reaction is proceeding right to left as written. (product to reactants)
• D) This reaction is at a state of chemical equilibrium.
