NPK fertilizer supplies which primary nutrients? MCQ with Answer and Explanation

NPK fertilizer supplies which primary nutrients?
A. Nitrogen, Phosphorus, Calcium
B. Sodium, Phosphorus, Potassium
C. Nitrogen, Phosphorus, Potassium
D. Nitrogen, Potassium, Calcium
Answer: Option C
Solution (By JKSSB Mock Tests)
NPK stands for Nitrogen (N), Phosphorus (P), and Potassium (K), the three primary macronutrients essential for plant growth. N promotes leaf growth, P aids root and flower development, K supports overall health. Fertilizer labels like 10-26-26 indicate the percentages of N, P₂O₅, and K₂O respectively. Calcium, magnesium, and sulfur are secondary nutrients, while Fe, Mn, Zn etc. are micronutrients.

Question #1
CFCs destroy ozone. Which atom is responsible?
A. Carbon
B. Oxygen
C. Chlorine
D. Fluorine

Correct Answer: Option C


Explanation:
UV radiation releases chlorine atoms from CFCs; Cl catalytically decomposes O₃: Cl + O₃ → ClO + O₂; ClO + O → Cl + O₂. One Cl atom can destroy thousands of ozone molecules.

Question #2
An example of a negative catalyst is:
A. V₂O₅ in Contact process
B. MnO₂ in decomposition of KClO₃
C. Fe in Haber process
D. Alcohol in chloroform

Correct Answer: Option D


Explanation:
Ethanol is added to chloroform to inhibit its oxidation to phosgene (COCl₂) – a negative catalyst. Others are positive catalysts that speed up reactions.

Question #3
An enzyme is a:
A. Inorganic catalyst
B. Negative catalyst
C. Lipid catalyst
D. Proteinaceous biocatalyst

Correct Answer: Option D


Explanation:
Enzymes are proteinaceous substances that act as biological catalysts, speeding up biochemical reactions in living organisms without being consumed. They are highly specific and work under mild conditions (pH, temperature). Examples: amylase breaks down starch, pepsin digests proteins. Inorganic catalysts are like Pt, Ni. Lipids are fats, not catalysts. Negative catalysts (inhibitors) slow reactions. Enzymes may be deactivated by high temperature or extreme pH.
