Question

The molar heat capacity of oxygen at constant pressure can be
expressed as follows: Cp,m = a + bT, where a = 6.15 cal mol^-1 K^-1
and b = 0.0031 cal mol^-1 K^-2. a) 2 mols of oxygen have been heated up reversibly from 27 ºC to 127 ºC, at a constant pressure of 1 atm. Calculate the w, q, ΔU and ΔH of the process. b) Same thing, assuming an isocoric process. The oxygen behaves as an ideal gas.

The molar heat capacity of oxygen at constant pressure can be
pressed as follows: Cp,m = a + bT, where a = 6.15 cal mol:1 K1
d b = 0.0031 cal mol·1 K-2. a) 2 mols of oxygen have been heated
reversibly from 27 °C to 127 °C, at a constant pressure of 1 atm.
culate the w, q, AU and AH of the process. b) Same thing,
uming an isocoric process. The oxygen behaves as an ideal gas.
