What is the role of nickel in hydrogenation of vegetable oil?
Answer and explanation
Correct answer: Catalyst
Hydrogenation is an addition reaction in which hydrogen is added to carbon-carbon double bonds of unsaturated vegetable oil, increasing saturation and often making the fat more solid. Nickel provides a surface that helps the reaction proceed faster by lowering the effective activation barrier, while it is regenerated rather than used up overall. Thus option A is correct. Nickel is not the solvent, an acid-base indicator, or the fuel in this process.
