p-Nitrophenol does have a higher $\mathrm{p}K_\mathrm{a}$ than carbonic acid (7.15 vs 6.3), the two logarithms differ by less than one unit, if we render the acidic species in carbonic acid as $\ce{CO2}$ rather than $\ce{H2CO3}$.So the equilibrium constant in the reaction $$\ce{p-C6H4(NO2)OH + HCO3- <=> p-C6H4(NO2)O- + CO2 + H2O}$$ is close to $1$ and a large percentage of the p-nitrophenol

The extent of reduction is about 6 percent for o-nitrophenol, 10 percent for m-nitrophenol and 14 percent for p-nitrophenol. The nitrophenols also undergo oxidation to a very small extent (less than 1 percent); o-nitrophenol yields traces of nitroquinol, m-nitrophenol, nitroquinol and 4-nitrocatechol and p-nitrophenol, 4-nitrocatechol.
