2) Mustard gas, used in chemical warfare in World War I, has been found to be an effective agent in the chemotherapy of Hodgkin's disease. It can be produced according to the following reaction: SCl (g)+ 2C H, (g)S(CH2CH2CI)2 (g) An evacuated 5.0 L flask at 20.0°C is filled with 0.258 mol SC12 and 0.592 mol C2H4. After equilibrium is established, 0.0349 mol mustard gas is present. (a) What is the partial pressure of each...

Phosgene (COCl2) is a nasty gas used occasionally in warfare. It blisters your lungs! Consider the reaction COCl2(g) ⇀↽ CO(g) + Cl2(g) and the thermodynamic data Species ∆H0 298 S 0 298 (kJ/mol) (J/mol · K) COCl2(g) −223.0 289.2 CO(g) −110.5 197.6 Cl2(g) 0 223.0 Calculate Kp at 623 K.
17. Phosgene, substance used in poisonous gas warfare a during World War I, is so named because it was first on a mixture of carbon prepared by the action of sunlight from the Greek monoxide and chlorine gases. Its name comes Words phos (light) and genes (born of). Phosgene has the following elemental composition: 12.14% C, 16.17% O, 71.69% and Ci by mass. is 98.9 g/mol. 10pt/ea this compound.

A United Nations toxicologist studying the properties of mustard gas, S(CH2CH2CI)2, a blistering agent used in warfare, prepares a mixture of 0.675 M SCI, and 0.973 M C H, and allows it to react at room temperature (20.0°C): SC12(g) + 2 C2H4() = S(CH,CH,CI), () At equilibrium,[S( CH,CH,CI)21 -0.350 M. Calculate Kp.
(15 points): Phosgene (COC2) is a highly toxic gas that was used as a chemical warfare agent in World War l. Although it is now banned for that purpose by international agreement, phosgene is still produced for industrial uses (where it must be handled very carefully!) It forms at high temperatures from a mixture of carbon monoxide and chlorine gases: 2. CoB)+ Cl2(8)COCI2(8) Kc 4.95 at 600. K If 7.5 atm worth of each reactant are pumped into a 5.00x103...
