\(A ( g ) \rightarrow 2 B ( g )+ C ( g )\) is a first order reaction. The initial pressure of the system was found to be \(800\,mm\,Hg\) which increased to \(1600\,mm\,Hg\) after \(10\,min\). The total pressure of the system after \(30\,min\) will be \(.........\,mm\,Hg\). (Nearest integer)
- A \(2100\)
- B \(2000\)
- C \(2300\)
- D \(2200\)
Answer & Solution
Correct Answer
(D) \(2200\)
Step-by-step Solution
Detailed explanation
\(t _{\frac{1}{2}}=10\) minutes \(\left( P _{ A }\right)_{30 \min }=\left( P _{ A }\right)_0\left(\frac{1}{2}\right)^{30 / 10}\) \(\left( P _{ A }\right)_{30 \min }=100\,mm\,Hg\) \(A ( g ) \rightarrow 2 B ( g )+ C ( g )\)…
