Step-by-step solution
(i) Ni in the presence of Hydrogen: a) Zieglar-Natta catalyst: This is likely a reaction involving the hydrogenation of an unsaturated compound (like an alkene or alkyne) using nickel as a catalyst. The ZieglarNatta catalyst is typically used for polymerization reactions, but it can also be used for hydrogenation under certain conditions. b) Contact process: This is a process used to produce sulfuric acid. It involves the oxidation of sulfur dioxide to sulfur trioxide using a catalyst (usually vanadium pentoxide).
