Does anyone know how to explain how to do this for me? "Consider the following equillibriated system: 2NO2(g)----2NO(g)+O2(g). If the Kp value is 0.860, find the equillibrium pressure of the O2 gas if the NO2 gas pressure is 0.520 atm and the PvNO is 0.300 atm at equillibrium."

Kp=Pproduct/Preactants (P are at equilibrium) the kp recation for you would be Kp=(pNO)^2*(pO2)/(pNO2)^2 (pNO and pNO2 are squared due to the coefficiant being 2 in the equation) and rearrange the equation to solve for O2(g)
