Question

I AM TAKING A TIMED QUIZ PLEASE HELP MISSING TWO QUESTIONS
Determine which of the following is the correct equilibrium expression for the chemical reaction:
N2 (g) + 3Cl2 (g) 2NCl3 (g)

Answer 1

Kc = [NCl]6/([N]2[Cl]6)
Kc = ([N2][Cl2]3)/[NCl3]2
Kc = ([N]2[Cl]6)/[NCl]6
Kc = [NCl3]2/([N2][Cl2]3)

Answer 2

which do you think it is

Answer 3

This should help

Answer 4

It's the last one, am I correct??? @Australopithecus

Answer 5

It is kind of unethical for me to help you if I know you are writing a quiz even though I just did confirming answers is where I draw the line. If you think that is the correct answer than submit it.

Answer 6

then*

Answer 7

As long as you followed the formula I provided you are fine

Answer 8

also I apologize for the poor grammar not a 100% right now but I am a 100% sure that information I provided you is correct.

Answer 9

Do you have another question?

Answer 10

I do yes @Australopithecus

Answer 11

Let me post it

Answer 12

For which of the following reactions will a decrease in pressure shift the equilibrium to the left?

2A2 (g) + B2 (g) -> 2A2B (g)
2AB (g) -> A2 (g)+ B2 (g)
2A2F3 (g) -> 4A (g) + 3F2 (g)
2B (s) + 2HA (aq) -> 2BA (aq) + H2 (g)

Answer 13

I feel that the answer is B

Answer 14

When you decrease pressure molecules will not hit into each other as often and therefore not react as often.

Answer 15

Also note the more molecules you have to have collide the less chance they will collide in the right way to cause a reaction to occur

Answer 16

physically a decrease in pressure means the molecules are farther apart in space

Answer 17

actually to change this, also note the more molecules you have to have collide the less chance they will collide at all or even in the right way to cause a reaction to occur

Answer 18

Its like if you had 2 people each with a ball and you wanted them to throw both the balls so that they hit each other.

Now imagine you have 3 people each with a ball and you wanted them to throw three balls so that they hit eachother.

Logically you would say that the people with the three balls would have less chance of being successful at hitting them together.


Now imagine the balls have a few pegs and grooves in them. It would be considered even less likely that the 3 balls would come together correctly so that the pegs fit into the grooves than the 2 balls

Answer 19

A decrease in pressure causes the people throwing the balls to be farther apart. Therefore logically the people throwing the three balls would have even less of a chance than those with two balls

Answer 20

let me know if you follow

Answer 21

I follow

Answer 22

alright awesome I hope you do well :D

Answer 23

If the left side doesnt react as readily as the right side in a equilibrium chemical reaction

the left side chemicals will build up

If the right side doesnt react as readily as the left side in a equilibrium chemical reaction

the right side chemicals will build up

Answer 24

Just putting this out there just to make sure you dont make an incorrect conclusion

Answer 25

Also a shift in equilibrium to the left means that there will be more reactants existing
a shift to the right means more product will exist
