The answer should be negative because gas will cool down during the throttling process molecules are doing work to cover repulsive intermolecular force, causing them to move further apart.

For an ideal gas, μ = 0, because ideal gases are neither warm nor cool upon being expanded at constant enthalpy.
If μ is +ve, then the temperature will fall during throttling.
If μ is -ve, then the temperature will rise during throttling.
If μ is +ve, then the temperature will fall during throttling.
If μ is -ve, then the temperature will rise during throttling.
