Consider the following gas phase reaction being carried out in a closed vessel at \(25°C\).
\(2A(g) \rightarrow 4B(g) + C(g)\)
| time (min) | total pressure of the system (mm Hg) |
|---|---|
| \(30\) | \(300\) |
| \(\infty\) | \(600\) |
- A 15
- B 20
- C 25
- D 30
Answer & Solution
Correct Answer
(B) 20
Step-by-step Solution
Detailed explanation
For the given gas phase reaction: \(2A(g) \rightarrow 4B(g) + C(g)\) Let the initial pressure of \(A(g)\) be \(P_0\). At \(t = 0\): \(P_A = P_0\), \(P_B = 0\), \(P_C = 0\) At \(t = t\): \(P_A = P_0 - 2p\), \(P_B = 4p\), \(P_C = p\) Total pressure at time \(t\),…
