Question

What is the equilibrium constant for the chemical equation:

1. N2 (g) + 3H2 (g) ↔ 2NH3 (g)

At equilibrium, the concentration of N2 is 2.5 x 10-4 M, the concentration of H2 is 6.4 x 10-3 M, and the concentration of NH3 is 5.3 x 10-2 M.

Write out the equilibrium constant, Keq, and show you work.

2. Mg3P2 (s) ↔ 3Mg+2 (aq) + 2P-3 (aq)

At equilibrium, the concentration of Mg3P2 is 5.5 x 10-6 M, the concentration of magnesium ions is 7.2 x 10-5 M, and the concentration of phosphide ions is 9.8 x 10-8 M.

Write out the equilibrium constant, Keq, and show you work.

Answer 1

x= 1 /5 y+ 4 /5

Step-by-step explanation:

Let's solve for x.

10x−2y=8

Step 1: Add 2y to both sides.

10x−2y+2y=8+2y

10x=2y+8

Step 2: Divide both sides by 10.

10x /10 = 2y+8 /10 x= 1 /5 y+ 4 /5
