The rate law for hydrolysis of this acetamide, `CH_(3)CSNH_(2)`, is :
`CH_(3)-underset(S)underset(||)C-NH_(2)+H_(2)Ooverset(H_(2)O)rarrCH_(3)-overset(O)overset(||)C-NH_(2)+H_(2)S`
Rate= K [thioacetamide]`[H^(+)]`
In which of the following solutions, will the rate of hydrolysis of thioacetamide (TA) is least at `25^(@)C` ?

Options

A. `0.1 "M TA" + 0.20"M HNO"_(3)`
B. `0.1 "M TA" + 0.20"M CH"_(3)COOH_(3)`
C. `0.1 "M TA" + 0.20"M HCOOH"`
D. `0.15 "M TA" + 0.15"M HCl"`

Answer

B
