A gas expands against a variable external pressure given by p = 10/V atm, where V is the volume at each stage of expansion. in expanding from 10 L to 100 L, the gas undergoes a change in internal energy ΔU = 418 J. How much heat has been absorbed?

HA + OH- = H2O + A- + q1 kJ

H+ + OH- = H2O + q2 kJ

The enthalpy of dissociation of HA is
