Question

Consider the following reaction where K, =10.5 at 350 K 2 CH2Cl2 (8) CH, (8)+ CC4 (B) A reaction mixture was found to contain 1.21x10 moles of CH,Cl2 (g), 2.60x102 moles of CH4 (g), and 4.36x10 moles of CCI4 (g), in a 1.00 liter container Indicate True (T) or False (E) for cach of the following: 1. In order to reach equilibrium CH Cl(g) must be consumed 2. In order to reach equilibrium K, must decrease. 3. In order to reach equilibrium CH, must be produced 4. Qe is less than K 5. The reaction is at equilibrium. No further reaction will occur Submit Answer Retry Entire Group 8 more group attempts remaining

2 CH2 Ch. chucos & caluca, Kc = 10:5 [CH₂Cl2] = 1.21x10 mot 21121815²m [ccm]= 4:36x10 ml = 4.36x10 m [C-in) = 2:00x10*mol = 2.6px 162m . Qc = [2.60x102][4.36X16*)774 [1:21x10-272 . As Qc <kcl so reaction möves forward 12. Tiſ 9 ſ 1 Statement 1 is true in reaction CH2Cl2 consumed a Statement 2 is [false] Ke depends on temperature only & here Qc wie increase. statement 3 is [True) Chu will be produced, Statement 4 is Toue) Qd<kc. Statement 5 is Falsel reaction moves forward.
