For the reaction, Bror +5Br+ eH. ? 3Bn + 3HO.«apanoaa tme. is -AlH yAt at the same instant?(1)26 x10 ws (2) (4)9.0 102 Ws for the systm H (3) the concentration of c ie 15. Which of these situations will result if some CHg)is added to the equlibium reaction below (1) Hz will be (4) No change will occur consumed (2) More CH4 and HO wil be produced (3) Mom CO b.need 16. For the following reaction at equilbrium, which gives a change that will sht te position of equlbrium to Tavor formation of more products? 2NOBrg) 2NOg) Brig) H-30kdl (11 Lower the temperature (2) Increase the total pressure by decreasing the volume (4) Remove Brz (3) Ads more NG 17. The equilibrium constant expression for the reaction Bra?g) SFg)2Fg) 18. For the equilibrium reaction below which one of these factors would cause the equilibrium constant to increase? (1) Add SOa gas (2) Remove O2 gas (3) increase the temperature (4) add a catalyst 19. The following reactions occur at 298 K. Arrange them in order of increasing tendency to proceed to completion (least completion to greatest completion) 2. C(s)+ H20(g)CO(g)+ Halg) K-1.6 x 101 K 32x10 K 46x10 (1)441Explanation / Answer
Ans 12 : 1) SnO2 (s) + 2H2 (g) = Sn (s) + 2H2O (g)
In this reaction , the number of gaseous species in each side of the reaction is same , such that the change in number of moles is equal to 0.
Kp = Kc (RT)n
where n is change in number of moles.
Since n = 0 , kp = kc
