It is an isothermal process so enthalpy change would be zero.
Because,
 increment H equals increment U plus increment n R T increment H equals increment U plus n R increment T T equals thin space C o n s tan t comma space s o increment U equals 0 comma space increment T equals 0 increment H equals 0
