Question

Consider the reaction below SO(0) + NOz(a) SO,(a) + NO(g) K = 0.25 at 900 °C If p802 4.0 atm, p803 - 1.0 atm, PNO 1.0 atm at a given point in time, what is the equilibrium partial pressure of so m ? Give your answer in 2 significant figures

Answer 1

first to calculate kp.

then to draw ICE table.

then using kp to find x.

then to find equilibrium partial pressure of SO2.
