Question

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answer the question 1) Which of the following statements is FALSE? A) When K<< 1, the reverse reaction is favored and the forward reaction does not proceed to a great extent. B) K>> implies that the reaction is very fast at producing products. When K>>> 1, the forward reaction is favored and essentially goes to completion. D) When K-1, neither the forward or reverse reaction is strongly favored, and about the same amount of reactants and products exist at equilibrium E) None of the above. 2) Give the direction of the reaction, if K - 1. A) The forward reaction is favored. B) The reverse reaction is favored. Neither direction is favored. D) If the temperature is raised, then the forward reaction is favored. E) If the temperature is raised, then the reverse reaction is favored. 3) Express the equilibrium constant for the following reaction CH4(8) +202() - CO2(8) +2H2018) A) K 1C02112H2012 B) K- ICH41120212 (CH4)0212 [CO2][H2012 (CH4]021 QK-1COH20) D) K=- (CH420212 1C021|2H 2012 [CO2][H2012 ICH4110212 E) K = 4) The equilibrium constant is given for one of the reactions below. Determine the value of the missing equilibrium constant. H268) + Br26) - HBr(e) HBr() - H2(g) + Br268) Ke=3.8. 104 Ke- ? 926 - 10-5 E) 53 x 10-5 D) 1.6 x 103 A) 64 . 10-4 B) 1.9 . 104

y option ② is correct option, ie, false becouse at kel, Constant amount of reachant and product exist at equilitinum not same amount Other ophons are correct Kect favers reverse kost favors forward (almost complet 2) K=1, Neither direction is Favered both are forward a backward rate are equal. so option © is correct Option & © is wrong because we don't have any information of temperature: 3. CHUCA, + 20213) CD269, + 2120 (7) k = [Product] [co2] [420]? [Reactant) [CH] [92]2 option is correct. rest all options are wrong 4) On reversing the equation the value of ke get reciprocal of it Kc, = 3.88104 kez = ? kg = K6 = 2.63x10-51 option © is correct
