What is the concentration (in \(\mathrm{mol} \mathrm{L}^{-1}\) ) of the product after \(20 \mathrm{~s}\) in the following reaction. Given that \(A \longrightarrow 3 B\), rate \(=k[\mathrm{~A}]^0\)
- A \(6.6 \times 10^{-2}\)
- B \(1.32 \times 10^{-1}\)
- C \(1.98 \times 10^{-1}\)
- D \(2.2 \times 10^{-2}\)
Answer & Solution
Correct Answer
(C) \(1.98 \times 10^{-1}\)
Step-by-step Solution
Detailed explanation
For the zero order reaction, \(A \longrightarrow 3 B\) the half-life is given by the formula \(t_{1 / 2}=A_0 / 2 k\) where, \(A_0\) is the initial concentration and \(k\) is the rate constant. After \(15 \mathrm{~s}\) the concentration of…
