can you please help me with problems 1 and 2? and explain how you did it? thank you!

1) Phosphine (PH3) decomposes at higher temperatures as follows: 2PH3(g)P2(g)+3H2(g)Kp=398 at 873K If the initial partial pressures are PPH3=0.0260atm,PP2=0.871atm,PH2= 0.517atm, find Qp and determine which direction the reaction proceedsin to reach equilibrium. 2) Given the following equilibria at a specific temperature NO(g)+1/2Br2(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)+Br2(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 equilibrium 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
