Carbon monoxide and molecular hydrogen react to form methanol. A 5.70 L reactor at 25.0 oC is charged with 2.56 bar of CO. The gas is then pressurized with H2 to give a total pressure of 3.26 bar. The reactor is sealed, heated to 350 o C to drive the reaction to completion, and cooled back to 25.0 o C. Compute the final partial pressure of each gas (in bar) after the reaction has occurred.
