Solution

The correct options are
A $H A (a q) + B O H (a q) ⟶ B A (a q) + H_{2} O : Δ H = - 42.3 k J / m o l$
B $H A (g) + B O H (a q) ⟶ B A (a q) + H_{2} O : Δ H = - 93 k J / m o l$
C $H A (g) ⟶ H^{+} (a q) + A^{-} (a q) : Δ H = - 55.7 k J / m o l$
$H A (a q) + B O H (a q) ⟶ B A (a q) + H_{2} O : Δ H = - 57.3 + 15 = - 42.3 k J / m o l$

$H A (g) + B O H (a q) ⟶ B A (a q) + H_{2} O : Δ H = - 70.7 + 20 + 15 - 57.3 = - 93 k J / m o l$

$H A (g) ⟶ H^{+} (a q) + A^{-} (a q) : Δ H = - 70.7 + 15 = - 55.7 k J / m o l$
