The catalyst used in the hydrogenation of oils is: MCQ with Answer and Explanation

Explanation:
Antoine Lavoisier, an 18th-century French chemist, is widely considered the father of modern chemistry. He transformed chemistry from a qualitative to a quantitative science, established the law of conservation of mass, debunked the phlogiston theory, and helped reform chemical nomenclature.

Explanation:
Henri Becquerel discovered radioactivity in 1896 while studying uranium salts. Marie and Pierre Curie further investigated radioactive elements. Rutherford studied alpha/beta radiation.

Explanation:
Lower activation energy means more molecules have energy to cross the barrier, increasing the reaction rate. Enthalpy (ΔH) and equilibrium constant remain unchanged. Catalyst does not affect stoichiometry.
