Equal weights of \(\mathrm{CH}_{4}\) and \(\mathrm{H}_{2}\) are mixed in an empty container at \(25^{\circ} \mathrm{C}\). the fraction of the total pressure exerted by \(\mathrm{H}_{2}\) is
- A \(1 / 9\)
- B \(1 / 2\)
- C \(8 / 9\)
- D \(16 / 17\)
Answer & Solution
Correct Answer
(C) \(8 / 9\)
Step-by-step Solution
Detailed explanation
Ratio of number of moles of \(\mathrm{CH}_{4}\) and \(\mathrm{H}_{2}\) are \[ \begin{array}{r} \mathrm{CH}_{4}: \mathrm{H}_{2}=\frac{x}{16} ; \frac{x}{2} \\ =1: 8 \end{array} \] Hence, partial pressure exerted by…
