Question

Calculate the enthalpy change for the given reaction from the data provided (kJ/mol):

HA(g) + B(g) → AHB(s)

(weak acid) (weak base) (Salt)

$Δ H_{n e u t r a l i z a t i o n} {H A (a q) [a t in f ini t e d i l u t i o n] / B (a q) [a t in f ini t e d i l u t i o n]} = - 40 k J / m o l$

$Δ H_{so l u t i o n} [H A (g)] = - 10 k J / m o l {at infinite dilution}$

$Δ H_{so l u t i o n} [B (g)] = - 5 k J / m o l {at infinite dilution}$

$Δ H_{so l u t i o n} [H A B (s)] = + 8 k J / m o l {at infinite dilution}$
