Consider the following reaction: h2(g)+i2(g)⇌2hi(g) complete the following table. assume that all concentrations are equilibrium concentrations in m. t(∘c) [h2] [i2] [hi] [kc] 25 0.0355 0.0388 0.922 − 340 − 4.60×10−2m 0.394m 9.6 445 4.90×10−2m 4.76×10−2m − 50.2 find kc at 25∘c. find [h2] at 340∘c. find [hi] at 445∘c.

These are three questions.

Explanation:

I will start by copying the table for better understanding of the data and the work to do.

T(∘C)       [H2]                    [I2]                     [HI]               [Kc]

25           0.0355               0.0388              0.922            -

340                                    4.60×10⁻²M       0.394M         9.6

445         4.90×10−2M      4.76×10⁻²M           −                50.2

The chemical equation that represents the equilibrium is also given:

From that equilibrium equation, you can fnd the expression of the equlibrium constant, Kc, as:

The calculations and explanations to answer the three questions are in the pdf file attached.
