Correct answer: B. (D) > (C) > (B) > (A)
Explanation
Producer gas is made by passing air (and sometimes steam) over hot coke, so nitrogen from the air dominates. A typical composition is about 50–55% N2, 25–30% CO, a few per cent CO2 and well under 1% CH4. The decreasing order is therefore N2 > CO > CO2 > CH4, i.e. (D) > (C) > (B) > (A).प्रोड्यूसर गैस गर्म कोक पर वायु (और कभी-कभी भाप) प्रवाहित करके बनाई जाती है, अतः वायु से आया नाइट्रोजन इसमें सर्वाधिक होता है। सामान्य संघटन लगभग 50–55% N2, 25–30% CO, कुछ प्रतिशत CO2 तथा 1% से भी कम CH4 होता है। अतः अवरोही क्रम N2 > CO > CO2 > CH4, अर्थात् (D) > (C) > (B) > (A)।More People, Development and Environment questions
