The equilibrium constant, Kc, for the following reaction is 77.5 at 600 K. CO(g) Cl2(g) COCl2(g) Calculate the equilibrium conce

Margarita [4]

Answer:

[CO] = 0.078M

[Cl2] = 0.078M

[COCl2] = 0.477M

Explanation:

Based on the reaction:

CO(g) Cl2(g) ⇄ COCl2(g)

<em>Where equilibrium constant, kc, is:</em>

kc = 77.5 = [COCl2] / [CO] [Cl2]

[] represents the equilibrium concentration of each gas. The initial concentration of each gas is:

[CO] = 0.555mol/1.00L = 0.555M

[Cl2] = 0.555M

And equilibrium concentrations are:

[CO] = 0.555M - x

[Cl2] = 0.555M - x

[COCl2] = x

<em>Where x is reaction coordinate</em>

Replacing in kc expression:

77.5 = [x] / [0.555M - x] [0.555M - x]

77.5 = x / 0.308025 - 1.11 x + x²

23.8719 - 86.025 x + 77.5 x² = x

23.8719 - 87.025 x + 77.5 x² = 0

x = 0.477M. Right answer

x = 0.646M. False answer. Produce negative concentrations

Replacing:

And those concentrations are the equilibrium concentrations

Answer:

Hypothesis and Data Collection

Part A-i think the glass with cold water will have more of a air bubble effect then the one with hot water

Part B-The glass with cold water is having more of a reaction but the water level in both of them are the same

Part C-yes, the glass with cold water had more of a reaction then the one with hot water

Analyze and Extend

Part A-yes, the glass with cold water had more of a reaction then the one with hot water

Part B-Becuase the reaction in the cold water was greater than the one in the hot water we can come to the conclusion that CO2 has a higher solubility in cold water

Part C-the soda that was left in the refrigerator wil have more "fizzing and bubbles" becuase it has higher solubility then the one left in the hot sun

Part D-There is now too much CO2 in the atmosphere and the tempertaures will continue to increase (this is why the summer time is hotter then the rest of the year)
