The heat capacity of Hydrgon may be represented by Cp= (1.554 + 0.0022 T) J/K mol. Compute the entropy changes for the system surroundings and the universe for the (a) reversible heating, as well as (b) irreversible heating of 1.0 mole of hydrogen from 300K to 600K. In (b) presume the surroundings to be at 600 K.
