NEET Botany Question (2026) — Solution
Options
- A. Between 0.5 and 0.95
- B. Less than 0.5
- C. 1.0
- D. Between 1.25 and 2
Answer
A. Between 0.5 and 0.95
Step-by-step solution
The respiratory quotient (RQ) is defined as the ratio of the volume of carbon dioxide evolved to the volume of oxygen consumed during respiration. From the given balanced chemical equation: Volume of CO _2 evolved = 102 Volume of O _2 consumed = 145 RQ = 102 145 0.7 The calculated value of RQ is approximately 0.7, which lies between 0.5 and 0.95. Answer: Between 0.5 and 0.95
