How much current is required to produce \(\mathrm{H}_2\) gas at the rate of \(1 \mathrm{cc} / \mathrm{sec}\) under STP?
- A \(2.33 \mathrm{~A}\)
- B \(6.0 \mathrm{~A}\)
- C \(7.9 \mathrm{~A}\)
- D \(8.61 \mathrm{~A}\)
Answer & Solution
Correct Answer
(D) \(8.61 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
\(2 \mathrm{H}^{+}+2 e^{-} \longrightarrow \mathrm{H}_2\) 1 mole of \(\mathrm{H}_2=22400 \mathrm{cc}\) at NTP 2 moles of electron required \(=2 \times 96500\) \(\therefore 1 \mathrm{cc}\) at \(\mathrm{NTP}=\frac{2 \times 96500}{22400}=8.616\)…
