Question

Consider the reaction, 2 BrCl (g) = Br2(g) + Cl2(g) at t = 25°C. This reaction is endothermic and has an equilibrium constant K = 0.0172 at this temperature. If at equilibrium the partial pressure of BrCl (g) is decreased by removing some BrCl, the response to the stress will be O A. no change O B. none of these O C. a shift to the right O D. unpredictable O E. a shift to the left

Answer 1

livey 2. Brolco - Brains & Cha cas at t=250 Reaction Endotheomic k=0.0172 Now, step → at Equilibrum the partial pressure of Brelo) - Decrease with the help of remove some Brel That means concentration of Brcleg, decrease Step The effect of Temprature depends Upon Reaction type is endothenic exothermic But the pressure and concentration effect Not related to cudothermic. Step ② So, Here due to decrease in Concaustration of Broly - According to le-chatelier principle, the position of Equilibinum will move, so that the conc? of "Brc" increase again. means More Bry tclo react to form more Brch means Morge Boch leed to form) a shift in left side - where more Brel form

SHORT Method 2 Brel - Brala) + chain) - Partial Pressure decrese Brd so, Conch of Brel (t) To maintain the Equilibrium We Need to form Bed mine So, Rn. Shif iu Brd side I left side
