***please solve it as soon as possible i really need it thank you!!!!

if possible please answer all seven quastions!!

1. Initially, we place 2 mol of A and 4 mol of B in a 0.5 L flask. At equilibrium, the flask contains 0.3 mol of C. Determine the value of K. A + B = 30 + 2D: 2. In a 500 ml flask, we put 6 mol of A, 6 mol of B, 4 moles of C and 9 mol of D. The value of K is 17.3. Is the system at equilibrium? If not, in which direction will the reaction proceed to attain equilibrium? Any + B = 200 + Dp 3. Calculate K, for a 2L container, this reaction was allowed to reach equilibrium: H2(g) + 12(g) =2HIO) where the number of moles at equilibrium were: H2 = 0.92 mol. 12 = 0.78 mol and HI - 6 mol 4. When 0.40 mol of PCs is heated in a 1L container, an equilibrium is established in which 0.25 mol of Cly is formed: Pisa) =PC13x0) + Clip) a) Find the equilibrium concentrations for all substances. b) What is the equilibrium constant? 5. When 3.0 mol HI, 2.0 mol H2 and 1.5 mol la are placed in a 1L container, the reaction proceeds towards equilibrium Halg) + 12()2H1) where K =50 Determine the direction of the reaction. 6. What amount of Hi is present at equilibrium when 2.0 mol of Hy is mixed with 1.0 mot of 12 in a 0.5L container H2(g) + 12() 21(c) where K = 50 7. What impact does each of the following have on the direction of this equilibrium and the Ke value: a) increase in pressure b) decrease in temperature and c) increase in temperature N2/+ 3H2/g) = 2NH3(g) +92KJ
