both please and thank you!!

3. How much NO forms in a sample of air heated to a high, constant temperature. N2(g)+O2(g)2NO(g) where the pressure of N2 is 0.79atm and O2 is 0.21atm with Kp=1.00105. 4. Name 3 ways you can change the equilibrium of the reaction below to yield more product. You must use temperature, concentration, and pressure in of each of the explanations. PCl3(g)+Cl2(g)PCl5(g)H=92.5kJ
