Chemistry

Gaseous hydrogen and solid arsenic oxide react to form gaseousarsine and water by the following reaction:

6H2 + As2O3 -->2AsH3 + 3H2O

Intro a 4.0L reactor are placed excessAs2O3 and 0.143 moles H2

(A) the reactikon is carried out at 125 degrees C, a temperatureat which all the water formed is gaseous. If all the hydrogenreacts, what is the pressure in the reactor after the reaction iscompleted?

(B) After the reaction is completed, the temperature isdecreased to 25 degrees C, a temperature at which a portion of thewater condenses. If all the hydrogen reacts, what is the mass ofwater that condenses? What is the pressure in the reactor after thereaction is completed and brought to this temperature?

(C) You conduct the reaction, but find that all the hydrogendoes not react. After the reaction temperatrue is decreased to 25degrees C, 0.90g of water has been found to condense. What is thefractional conversion of the reaction? What is the pressure in thereactor after the reaction is completed and brought to 25 degreesC.
