At \(T(\mathrm{~K})\) the molarity of \(\mathrm{CO}_2\) (in \(\mathrm{mol} \mathrm{L}^{-1}\) ) in 200 \(\mathrm{mL}\) of soda water packed under a pressure of 3.4 bar is \(\left(K_{\mathrm{H}}\right.\) of \(\mathrm{CO}_2\) in water is \(1.7 \times 10^3\) bar at \(T(\mathrm{~K}))\)

  1. A \(2.0 \times 10^{-2}\)
  2. B \(1.11 \times 10^{-1}\)
  3. C \(2.22 \times 10^{-1}\)
  4. D \(5.1 \times 10^{-2}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(1.11 \times 10^{-1}\)

Step-by-step Solution

Detailed explanation

Given, volume \(=200 \mathrm{~mL}\) pressure, \(p=3.4 \mathrm{bar}\) \(K_{\mathrm{H}}\) of \(\mathrm{CO}_2\) in water \(=1.7 \times 10^3\) bar According to Henry's law, \(p_{\mathrm{CO}_2}=K_{\mathrm{H}} \cdot \chi\) \(\chi=\frac{p_{\mathrm{CO}_2}}{K_{\mathrm{H}}}\)…
