Whatístech ngeo3Ruin+4uBrdnotlised 9Which of the following contains a complex anion? A.K?CoCla] B.KJFe(CNMC.[Cr(NH).?12)Cl D, none listed 10. For the system: Sio2 (s) +4HF ()SiF4 (B) +2H20 (g) initially at equilibrium, a shift to CONSUME more HF will occur if: A. more H20 (g) is added to system B. HF (g) is removed from the system C. more solid SiO2 is added to system D. the pressure decreases by increasing the volume of the container 11. Which of the following reactions will exist in equilibrium primarily as products? A. K-1 B, K-1.3x10° C. K-.100 D.?-2.8 x 10'12Explanation / Answer
10) HF present on reactants side. Shift to concume more HF means reaction moves towards products side..
Addition of reactants or removal of products will shift the equilibrium towards products side.
Decreasing pressure will shift equilibrium towards more number of gaseous molecules side.
Hence, the correct option is
C. More solid SiO2 is Added to system.
11)
If K > 1 products side favored
If K= 1 reaction at qequilibrium
If K < 1 reactants side favored
Hence correct option is (B) 1.3×10^9
