75 kPa of CO and 75 kPa of O2 were placed in a 5L vessel and allowed to react to form CO2. What is the total pressure of the vessel after complete reaction?

Solutions

Expert Solution

2 CO + O2    ----> 2 CO2
75          75                                    (initial)
-75        -75/2           +75              (change)
0              75/2           75               (final)

Total pressure = 75+ 75/2
                               = 75 + 37.5
                               = 112.5

Answer: 112.5 Kpa
