Question

The catalyst used for conversion of ethene to ethane is commonly __________.

Answer 1

• Ethene (${\mathrm{CH}}_2={\mathrm{CH}}_2$) is an organic molecule that has a double bond
• The conversion of Ethene to Ethane (${\mathrm{CH}}_3-{\mathrm{CH}}_3$) is known as Hydrogenation reaction because there is the addition of Hydrogen (${\mathrm{H}}_2$) molecule to the Ethene and it needs a catalyst to do this. The reaction is given below:
• $\underset{\mathrm{Ethene}}{{\mathrm{CH}}_2={\mathrm{CH}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}\stackrel{\mathrm{Ni}}{\to }\underset{\mathrm{Ethane}}{{\mathrm{CH}}_3-{\mathrm{CH}}_3\left(\mathrm{g}\right)}$
• Therefore, Nickel ($\mathrm{Ni}$) is used as the catalyst for the Hydrogenation reaction.
• Hence, the catalyst used for the conversion of Ethene to Ethane is commonly Nickel ($\mathrm{Ni}$).
