For the formation of NH3 from N2 and H2, N2(g) + 3H2(g) ↔ 2NH3(g) Kp = 4.34 x10-3 at 300ºC.

What is the value of Kp for the reverse reaction?

Combining Equilibrium Expression. (Note: this is like Hess’s Law and equilibrium together. If you have to reverse and equation make sure to take the reciprocal of the Kp value. Also if you have to double or triple an equation that means you should be squaring the equilibrium constant and not just multiplying by 2.

3) Given that, at 700K, Kp = 54.0 H2(g) + I2(g) ↔ 2HI(g)

Kp = 1.04 x 10-4 N2(g) + 3H2(g) ↔ 2NH3(g)

Find the value of Kp for 2NH3(g) + 3I2(g) ↔ 6HI(g) + N2(g)

Determine the Kc of the synthesis of ammonia from nitrogen and hydrogen,

N2(g) + 3H2(g) ↔ 2NH3(g) at 300ºC. The equilibrium amounts of N2 and H2 are 1.24 M and the NH3 equilibrium amount is 4.55 M .
