6. Hydrogenation of carbon-carbon 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)Hrn=174.53kj The calculated Kc at 2000K is 2.9108. But the process is run at lower temperature with the aid of a catalyst to prevent decomposition. Calculate Kc at 300K
