can you please help me with this question? thank you!

2) Given the following equilibria at a specific temperature NO(g)+K2Br2(g)NOBr(g)2NO(g)N2(g)+O2(g)Kp=5.3Kp=2.11030 a. Determine the Kp for the reaction N2(g)+O2(g)+Br(g)2 NOBr(g). b. Suppose at this temperature, an initial gas mixture contains 0.15atm of N2,0.050 atm of O2, and 0.020atm of Br2. Determine direction of reaction to approach equillibrium and final equilibrium partial pressures of N2,O2,Br2, and NOBr. Hint, would small x approximation be appropriate here? What would be the percent error in such an approximation
