hej er der nogen der kan hjælpe med denne opgave.
a) the work done on the surroundings at 1 bar pressure and 298 K when 0,200 mole H2O2 decomposes (volume occupied by 1 mole og gas at 1 bar and 273 K=22,7 dm3)
b) If the standard enthalpy of reaction is -98,2 kJ per mole of H2O2 what is the corresponding change in the internal energy of the system.
