Accumulation of lactic acid $(HC_3H_5O_3),$ a monobasic acid in tissues leads to pain and a feeling of fatigue. In a $0.10\, M$ aqueous solution, lactic acid is $3.7\%$ dissociates. The value of dissociation constant, $K_a,$ for this acid will be
$1.4 \times 10^{-5}$
$1.4 \times 10^{-4}$
$3.7 \times 10^{-4}$
$2.8 \times 10^{-4}$
The hydrogen ion concentration of $0.1\,N$ solution of $C{H_3}COOH,$ which is $30\%$ dissociated, is
Heat of neutralisation of weak acid and strong base is less than the heat of neutralisation of strong acid and strong base due to
