A chemist interrogates data........

Explanation:

......and we gots no data........

My text reports that for #3-C_6H_4(NO_2)(CO_2H)#, #pK_a=3.46#.

And for #4-C_6H_4(NO_2)(CO_2H)#, #pK_a=3.44#.

And so #"4-nitrobenzoic acid"# is SLIGHTLY more acidic than #"3-nitrobenzoic acid"#, but the difference in acidity is very marginal.
