Answer:

D. 29.2

Step-by-step explanation:

To calculate the equilibrium constant Kp for an equation of the form aA + bB ⇌ cC, use the following formula: Kp = (PC)c(PA)a(PB)b

For the equation H2(g) + I2(g) ⇌ 2HI(g), we have:

Kp= PHI2PH2 ⋅ PI2 = 66.6213.0 ⋅ 11.7 = 29.2

Marked correct on Gizmo :)

Answer:

Equilibrium constant is equal to
29.162

Step-by-step explanation:

If the reaction is of this form

aA(g) + bB(g) ⇄ cC(g) + dD(g)

Then , the Kp of this equation will be equal to


K_p =(P_C^cP_D^d)/(P_B^bP_A^a)

Given


P_c =
66.6 MPa and c is equal to two


P_A = 13.0 MPa


P_b = 11.7 MPa

Here a and b is equal to zero.

Substituting the given values we get -


K_p = (66.6^2)/(13*11.7)\\K_p = 29.162

Equilibrium constant is equal to
29.162
