Question

Calculate the value of kc if you rewrote the equation h2(g)+12s2(g)⇌h2s(g).

Answer 1

To calculate the value of Keq, we use the equation [HI]² [H₂] [12] and substitute the given values into the equation. The value of Keq is a constant that represents the equilibrium position of the reaction.

Step-by-step explanation:

We start by writing the Keq expression. Using the products over reactants approach, the Keq expression is as follows: [HI]² [H₂] [12]

We substitute these values into our equilibrium expression and solve for Keq:

Keq = [HI]² [H₂] × [12] / (0.156)² (0.022) (0.022)

The value of Keq, which has no units, is a constant for any particular reaction, and its value does not change unless the temperature of the system is changed. It does not depend on the initial concentrations used to reach the point of equilibrium.

Answer 2

To calculate the value of Kc for the given equation, we start by writing the Keq expression and substituting the values into it. The value of Kc, which is a constant, does not change unless the temperature of the system is changed and does not depend on the initial concentrations.

Step-by-step explanation:

We start by writing the Keq expression. Using the products over reactants approach, the Keq expression is as follows:

1. [HI]² [H₂] [12]

We substitute these values into our equilibrium expression and solve for Keq:

Keq

[HI]² [H₂] × [12]

(0.156)² (0.022) (0.022)

The value of Keq, which has no units, is a constant for any particular reaction, and its value does not change unless the temperature of the system is changed. It does not depend on the initial concentrations used to reach the point of equilibrium.
