Hydrogenation of carbon-carbon p bonds is important in the petroleum and food industries. The conversion of acetylene to ethylene is a simple example of the process:C₂H₂(g) + H₂(g) ⇄ C₂H₄(g)The calculated Kc at 2000. K is 2.9x10⁸. But the process is run at lower temperatures with the aid of a catalyst to prevent decomposition. Use ΔH° values to calculate Kc at 300. K.
