- $H_{2}$
- $He$
- $CO_{2}$
- $Ne$
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Partial pressure is directly proportional to the number of moles ($n = \text{mass} / \text{molar mass}$).
Step 2: Calculation
- $n(H_{2}) = 5/2 = 2.5$ mol - $n(He) = 8/4 = 2.0$ mol - $n(CO_{2}) = 50/44 \approx 1.13$ mol - $n(Ne) = 20/20 = 1.0$ mol
Step 3: Analysis
Neon ($Ne$) has the lowest number of moles (1.0).
Step 4: Conclusion
Since Neon has the fewest moles, it exerts the minimum partial pressure. Final Answer: (D)
