Answer #1

The equation for the reaction is:

X + Y2\rightarrow XY + Y

The equation for K is : K = [XY] * [Y] / ( [X] * [Y2])

Now the concentrations can be reduced to the count of the molescules since they occupy common volume.

a) [XY] = 4

[X] = 1

[Y2] = 1

[Y] = 2

K = 4 * 2 / (1 * 1 ) = 8.00

b)

[XY] = 2

[X] = 3

[Y2] = 2

[Y] = 2

K = 2 * 2 / (3 * 2 ) = 0.67

c)

[XY] = 3

[X] = 2

[Y2] = 1

[Y] = 3

K = 3 * 3 / (2 * 1 ) = 4.50

    1. The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation Kp=Kc(RT)Δn where R=0.08206 L⋅atm/(K⋅mol), T is the absolute temperature, and Δn is the change in the number of moles of gas (sum moles products - sum moles reactants). For example, consider the reaction N2(g)+3H2(g)⇌2NH3(g) for which Δn=2−(1+3)=−2. Part A For the reaction 3A(g)+2B(g)⇌C(g)...
