Question

Which changes occur when O2(g) is added to this system?
Given the system at equilibrium:

2POCl3(g) + energy <--> 2PCl3(g) + O2(g)

Which changes occur when O2(g) is added to this system?

1. The equilibrium shifts to the right and the concentration of PCl3(g) increases.
2. The equilibrium shifts to the right and the concentration of PCl3(g) decreases.
3. The equilibrium shifts to the left and the concentration of PCl3(g) increases.
4. The equilibrium shifts to the left and the concentration of PCl3(g) decreases.

Answer 1

4

Answer 2

lol confused the products with reactants its 4

Answer 3

hahaha anyway nice explanation :)

Answer 4

hey could you guys help me with this one question!
its really hard i have 100 questions to do

Answer 5

according to reference table I , which of these compounds is most stable?
ethane
alumonum oxide
ethyne
or carbon dioxide

Answer 6

the answer s 4...coz when u add O2...the concentration on the right hand side is more than the left...so the system moves from right to left (high concentration to low) when this happens 02 is used up so oxygen conc decreases

Answer 7

The reaction will go in reverse if you add excess product, if you add excess reactant it will go forward. As the system wants to maintain an equilibrium between the amount of products and reactants.

Answer 8

I would guess CO2 as it is extremely oxidized

Answer 9

i think it is Al203

Answer 10

It is the most stable form of carbon

Answer 11

Al2O3 would be more reactive as it is an electron acceptor, it would be a strong base

Answer 12

so its carbon dioxide right

Answer 13

I would assume so

Answer 14

alumonum oxide would be a strong base thus reactive, as the aluminum atoms would be highly electron definicent
ethane is stable but it is of a higher energy than CO2
ethyne Alkyne very unstable highly reactive acts as nucleophile

CO2 most stable form of carbon
when you oxidize carbon chains completely you end up with CO2 and H2O :)

Answer 15

yeah thats right thanks alot!
