Given the information for reaction 1 at a specific temperature; calculate kc for reaction 2 at the same temperature. reaction 1: 2ch4 (g) ⇄ c2h2 (g) + 3h2 (g) kc = 0.020 reaction 2: 2c2h2 (g) + 6h2 (g) ⇄ 4ch4 (g)

Kc for reaction 2 at the same temperature

The equilibrium constant or Kc is the price of the concentration product in the equilibrium state of the substance in the right segment divided by the product of the substance in the left section, each of which has a reaction coefficient raised

The equilibrium constant based on concentration (Kc) in a reaction

pA + qB -----> mC + nD

In reaction 1 2CH₄ (g) ⇄ C₂H₂ (g) + 3H₂ (g) Kc = 0.020

On reaction 2: 2C₂H₂ (g) + 6H₂ (g) ⇄ 4CH₄ (g)

From the 2 equation the above reaction shows that reaction 2 is the opposite of reaction 1 whose coefficient is multiplied by 2. Then the price of Kc reaction 2 is the square of the inverse price of Kc reaction 1

2CH₄ (g) ⇄ C₂H₂ (g) + 3H₂ (g) Kc = 0.020

Then reversed

C₂H₂ (g) + 3H₂ (g) ⇄ 2CH₄ (g)

Kc = 1 / 0.02 = 50

Then reaction 2 :

2C₂H₂ (g) + 6H₂ (g) ⇄ 4CH₄ (g)
