Nickel is used in the hydrogenation of alkenes because it
- AIncreases the yield of the product
- Blowers the activation energy of the reaction
- Cmakes the reaction more exothermic
- Dprevents a reverse reaction from occuring
Explanation
Nickel acts as a catalyst in the hydrogenation of alkenes, which increases the rate of reaction by providing an alternative reaction path with a lower activation energy.
