Give a balanced equation when:
(d) a mixture of ethene and hydrogen is passed over nickel at $200^{\circ}$ C

Open in App

Solution

The balanced equation is
$C_{2} H_{4} + H_{2} N i - - \to 200^{\circ} C_{2} H_{6}$
Product: ethane
This reaction is a hydrogenation reaction where ethene is passed over a catalyst like Ni at 200°C, or Pd, Pt at ordinary temperature. Two atoms of hydrogen are added with ethene gives ethane.
