7) Consider the following reaction: liter mol-sec 2 HI(g) → H₂(g) + 12 (g) k = 0.0969. Initially, a flask contained HI at a concentration of 0.670 M. At equilibrium, the concentration of [HI] in the flask was 0.125 M. From this information, answer the following questions: a. What is the equilibrium constant for the above reaction? b. What is the rate constant for the reverse reaction? Note: remember that ratef=rater, and assume this is a one-step mechanism (the reactions shown have the correct molecularity).

7) Consider the following reaction:
liter
mol-sec
2 HI(g) → H₂(g) + 12 (g)
k = 0.0969.
Initially, a flask contained HI at a concentration of 0.670 M. At equilibrium,
the concentration of [HI] in the flask was 0.125 M. From this information,
answer the following questions:
a. What is the equilibrium constant for the above reaction?
b. What is the rate constant for the reverse reaction? Note: remember
that rate= rater, and assume this is a one-step mechanism (the
reactions shown have the correct molecularity).
Answer: 0.6, 0.06
