Chapter 15, Problem 73AP

At a certain temperature and a total pressure of 1.2 atm, the partial pressures of an equilibrium mixture

$\text{2A}\left(g\right)\rightleftarrows \text{B}\left(g\right)$

are $P_{\text{A}}\text{= 0}\text{.60 atm and }{P}_{\text{B}}\text{= 0}\text{.60 atm}\text{.}$ (a) Calculate the $K_{\text{P}}$ for the reaction at this temperature. (b) If the total pressure were increased to 1.5 atm, what would be the partial pressures of A and B at equilibrium?
