Mustard gas, used in chemical warfare in World War I, ha been found to be an effective agent in the chemotherapy of Hodgkin’s disease. It can be produced according to this reaction:

An evacuated 5.00-L flask at 20.0 °C is filled with 0.258 mol SCl₂ and 0.592 mol C₂H₄ and sealed. After equilibrium is established, 0.0349 mol mustard gas is present.

(a) Calculate the partial pressure of each gas at equilibrium.

(b) Calculate K_c at 20.0 °C.
