At a certain temperature and total pressure of 1.2 atm, the partial pressures of an equilibrium mixture for 2A (g) <----> B (g)are PA = 0.60 atm, and PB = 0.60 atm. After a disturbance, the system regains equilibrium with a total pressure of 1.6 atm. What is the partial pressure of A at the new equilibrium?________atm(my first answer was 0.8 but that was wrong and the tutorial mentioned it would have to be eventually solved with the quadratic formula but though I calculated several different times, I could not come up with the right answer)
