Question

Use LeChatelier's principle to predict the effect (increase. decrease, no change) that the change given in the first column of the table below has on the quantity in the second column for the following equilibrium system: Consider the exothermic reaction: 2 HI(g) + Br2(g) 2 HBr(g) + I2(s) Br2(g) is a red brown vapor, I2(s) is a purple-black solid HI and HBr are both colorless gases. Brackets ([ ]) mean molarity, i.e. mol/Liter. Remember, 'mol/Liter' is concentration, which is not the same as 'mass' or 'amount' of material. Circle the appropriate letter: Describe in one or two sentences what differences you would expect in the appearance of the system when it reaches its new equilibrium after a decrease in temperature.

Explanation / Answer

2HI(g) + Br2(g) <-----> (equilibrium) 2HBr(g) + I2(s)

1) If [HBr] increases Equilibrium shifts towards backward direction

2) if Br2 is removed than [HI]: Equilibrium shifts towards backward direction

3) if Temperature decreases that Kc: generally increses rate of reaction with Temperature. so Kc decreases

4) if [HI] increases than [Br2]: Equilibrium shifts towards forward direction

5) if Temperature increases than [HBr] :Equilibrium shifts towards backward direction

6 ) after a decrease in temperature Equilibrium shifts towards forward direction. at low temperature the formation solid more favorable
