Now consider the reaction at 298 K. At this temperature, the reaction has an equilibrium constant Kₑᵩ = 2.00 x 10⁻¹⁸

If the reaction is initiated by adding a catalyst to a flask containing C₂H₆(g) at a pressure of 2.14 bar, what will be the partial pressure of H₂(g) and C₂H₄(g) at equilibrium?

The partial pressure of H₂ is:
