The reaction 2CH4(g)⇌C2H2(g)+3H2(g) has an equilibrium constant of K = 0.154. If 6.30 mol of CH4, 4.20 mol of C2H2, and 11.15 mo

Answer:

C₂H₂ + 3H₂ ⟶ 2CH₄

Explanation:

The initial concentrations are:

[CH₄] = 6.30 ÷ 6.00 = 1.05 mol·L⁻¹

[C₂H₂] = 4.20 ÷ 6.00 = 0.700 mol·L⁻¹

[H₂] = 11.15 ÷ 6.00 = 1.858 mol·L⁻¹

2CH₄ ⇌ C₂H₂ + 3H₂
