SCl +2 C,H * S(CH;CH;CI)208) 4. weapon used in World War II and more recently in the Middle East has been shown to have a therapeutic index that enables it to be used as an effective agent in the chemotherapy of Hodgkin's disease. It can be generated according to the reaction: Mustard gas, a chemical An evacuated 3-liter flask at 29.5°C is filled with 0.139 mol of SCI, and 0.269 mol C,H,. After equilibrium is established, 0.01765 mol mustard gas is present. a. What is the partial pressure of each gas at equilibrium? b. What are the equilibrium constants Kc and Kp at 29.5°C?

Decide whether each of the following statements is true or false.  If false, change the wording of the statement to make it true.   a) Only the concentration of CO2 appears in the equilibrium expression for the reaction: CaCO3 (s) ↔ CaO (s) + CO2 (g). B) For the reaction CaCO3 (s) ↔ CaO (s) + CO2 (g), the value of K is numerically the same whether the amount of CO2 is expressed as molarity or as gas pressure.

Suppose a 500. mL flask is filled with 1.5 mol of SO, and 0.20 mol of SO2. This reaction becomes possible: 2 (3) 2S0, (g) + 0,(g) =2SO3(g, Complete the table below, so that it lists the initial molarity of each compound, the change in molarity of each compound due to the reaction, and the equilibrium molarity of each compound after the reaction has come to equilibrium. Use x to stand for the unknown change in the molarity of 0,. You can leave out the M symbol for molarity. 2 so, 02 so, initial ? change equilibrium olo
