A(g) <-----> B(g) is 10. The double head arrow represents an equilibrium arrow, not a resonance arrow. A reaction mixture, initially contains 11 mol of A and 0 mol of B in a fixed volume of 1 L.
When equilibrium is reached, how many moles of A and how many mole of B are present?
At a pressure of 1.00 atm and a temperature of 20 degree Celsius, 1.72 g CO2 will dissolve in 1 L of water. How much CO2 will dissolve if the pressure is raised to 1.35 atm and the temperature stays the same?
