For a weak acid HA, Ostwald’s dilution law is represented by the equation
- \(\mathrm{K}_{\mathrm{a}}=\frac{\alpha \mathrm{c}}{1-\alpha^{2}}\)
- \(\mathrm{K}_{\mathrm{a}}=\frac{\alpha^{2} \mathrm{c}}{1-\alpha}\)
- \(\alpha=\frac{\mathrm{K}_{\mathrm{a}} \mathrm{c}}{1-\mathrm{c}}\)
- \(\mathrm{K}_{\mathrm{a}}=\frac{\alpha^{2} \mathrm{c}}{1-\alpha^{2}}\)
Answer
(B) K _ a = ^ 2 c 1-
