A mixture of 0.5940 M CO and 0.3950 M Cl2 is enclosed in a vessel and heated to 1000 K . CO(g)+Cl2(g)↽−−⇀COCl2(g)c=255.0 at 1000 K Calculate the equilibrium concentration of each gas at 1000 K

[CO] = 0.2064M

[Cl2] = 0.0074M

[COCl2] = 0.3876M

Explanation:

Based on the reaction, Kc at 1000K is:

Kc = 255.0 = [COCl2] / [CO] [Cl2]

Where [] are concentrations at equilibrium

As the reaction is 1:1, the concentrations at equilibrium are:

[CO] = 0.5940M - X

[Cl2] = 0.3950M - X

[COCl2] = X

Where X is reaction coordinate

Replacing:

255.0 = [X] / [0.5940 - X] [0.3950 - X]

255.0 = X / 0.23463 - 0.989 X + X²

59.8307 - 252.195 X + 255 X² = X

59.8307 - 253.195 X + 255 X² = 0

Solving for X:

X = 0.605M. False solution because produce negative answers

X = 0.3876M. Right solution.

Replacing:

[CO] = 0.5940M - 0.3876M

[Cl2] = 0.3950M - 0.3876M

[COCl2] = 0.3876M

[CO] = 0.2064M

[Cl2] = 0.0074M

[COCl2] = 0.3876M

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
