In the Haber process for the manufacture of ammonia, the catalyst used is: MCQ with Answer and Explanation

In the Haber process for the manufacture of ammonia, the catalyst used is:
A. Nickel (Ni)
B. Platinum (Pt)
C. Finely divided Iron (Fe)
D. Vanadium pentoxide (V₂O₅)
Answer: Option C
Solution (By JKExamLibrary)
The Haber process synthesizes ammonia from nitrogen and hydrogen (N₂ + 3H₂ ⇌ 2NH₃). Finely divided iron acts as the catalyst, often with molybdenum as a promoter, to increase the rate of reaction at high pressure and moderate temperature. V₂O₅ is used in the Contact process.

Question #1
Soap molecules have two ends with different properties. They are:
A. Both A and B
B. Lipophobic and hydrophobic
C. Hydrophobic and hydrophilic
D. Hydrophilic and lipophilic

Correct Answer: Option A


Explanation:
A soap molecule has a long hydrocarbon chain which is hydrophobic (water-repelling) or lipophilic (fat-loving), and an ionic head (usually -COO⁻Na⁺) which is hydrophilic (water-loving) or lipophobic (fat-repelling). Both A and B correctly describe these dual properties essential for cleaning action.

Question #2
Assertion (A): The noble gases are placed in Group 18. Reason (R): They have a completely filled outermost shell (except Helium) and zero valency.
A. A is true but R is false.
B. Both A and R are true but R is NOT the correct explanation of A.
C. Both A and R are true and R is the correct explanation of A.
D. A is false but R is true.

Correct Answer: Option C


Explanation:
Noble gases have completely filled valence shells (ns²np⁶, except He which is 1s²), making them highly stable and unreactive with a valency of zero. Because of this unique stability and distinct electronic configuration, they form a separate group, Group 18, in the modern periodic table.

Question #3
During electrolysis, the amount of substance deposited depends on the quantity of electricity passed. This is:
A. Ohm's law
B. Faraday's first law
C. Graham's law
D. Faraday's second law

Correct Answer: Option B


Explanation:
Faraday's first law of electrolysis: Mass of substance deposited or liberated is proportional to the charge passed (m = ZQ). Z is electrochemical equivalent. Second law relates masses of different substances to equivalent weights for same charge. Ohm's law is V=IR, Graham's law for diffusion. Faraday's laws are quantitative.
