A reversible cyclic process for an ideal gas is shown below. Here, P, V, and T are pressure, volume and temperature, respectively. The thermodynamic parameters q, w, H and U are heat, work, enthalpy and internal energy, respectively.

The correct options(s) is (are)

A

$$q_{AC}=\triangle U_{BC}$$ and $$W_{AB}=P_{2}(V_{2}-V_{1})$$

B

$$W_{BC}=P_{2}(V_{2}-V_{1})$$ and $$q_{BC}=\triangle_{H_{AC}}$$

C

$$\triangle H_{CA}<\triangle U_{CA}$$ and $$Q_{AC}=\triangle U_{BC}$$

D

$$\triangle q_{BC}=\triangle H_{AC}$$ and $$\triangle H_{CA}>\triangle U_{CA}$$
