Match List I with List II:
Choose the correct answer from the options given below:
Let’s match the processes with their respective catalysts:
A. Haber process: This is the process for the industrial synthesis of ammonia (N₂ + 3H₂ → 2NH₃), and the catalyst used is Fe (iron).
Thus, A-I.
B. Wacker oxidation: This process involves the oxidation of alkenes to carbonyl compounds (like aldehydes or ketones), and the catalyst used is PdCl₂ (palladium chloride).
Thus, B-II.
C. Wilkinson catalyst: This catalyst is used in the hydrogenation of alkenes, and its composition is [(C₆H₅)₃RhCl] (tris(triphenylphosphine) rhodium chloride).
Thus, C-III.
D. Ziegler catalyst: This is used in the polymerization of alkenes, and the catalyst used is TiCl₄ with Al(C₂H₅)₃ (titanium tetrachloride and triethylaluminum).
Thus, D-IV.
Thus, the correct answer is (2) A-I, B-II, C-III, D-IV.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
