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?
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
