9. A mixture of carbon monoxide, hydrogen, and methanol is at equilibrium. The balanced chemical equation is: CO(g) + 2 H2(g) ⇌ CH3OH(g). At equilibrium, the mixture contains 0.0960 M CO, 0.191 M H2, and 0.150 M CH3OH. What is the value for Kc?

The value for the equilibrium constant Kc is 42.83

Explanation:

Step 1: Data given

At equilibrium, the mixture contains:

0.0960 M CO,

0.191 M H2,

and 0.150 M CH3OH.

Step 2: The balance equation

CO(g) + 2 H2(g) ⇌ CH3OH(g).

Step 3: Calculate the value for the equilibrium constant Kc

Kc = [CH3OH] / [CO]*[H2]²

⇒with Kc = the equilibrium constant = TO BE DETERMINED

⇒with [CH3OH] = 0.150 M

⇒with [CO] = 0.0960 M

⇒with [H2] = 0.191 M

Kc = 0.150 M / (0.0960 M *( 0.191 M)²)

Kc = 42.83

The value for the equilibrium constant Kc is 42.83

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
