The equation of state for one mole of a gas is \( P V=R T+B P \), where \( B \) is a constant, independent of temperature. The internal energy of fixed amount of gas is the function of temperature only. If one mole of the above gas is isothermally expanded from \( 12 \mathrm{~L} \) to \( 22 \mathrm{~L} \) at a constant external pressure of 1 bar at \( 400 \mathrm{~K} \), then the change in enthalpy of the gas is approximately \( (\mathrm{B}=2 \mathrm{~L} / \mathrm{mol}) \)
(a) 0
(b) \( -3.32 \mathrm{~J} \)
(c) \( -332 \mathrm{~J} \)
(d) \( -166 \mathrm{~J} \)
