The volume of the vessel containing unsaturated water vapor was increased by a = 20%, while b = 15% of the steam mass evaporated from the vessel. Then the temperature of the steam was increased by y=50%, as a result 6=10% of the H20 molecules disintegrated to form molecular hydrogen H2 and oxygen O2. As a result, the pressure in the vessel changed compared to the initial one by dр=1.0 • 103 Pa. What was the initial vapor pressure in the vessel?
