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.

it should be all of them because it asks if you included all of those in your answer
