A. K = 0
B. Q > K
C. Q < K
D. Q = K

Answer 1

@Hoslos @rvc

Answer 2

B when reaction quotiont is greater
am i right

Answer 3

Do not they specify weither it is a composition or decomposition reaction?

Answer 4

No they don't specify.

Answer 5

Then it shall be B.

Answer 6

Thanks!

Answer 7

Which of the following is always true about a reaction at equilibrium?

A. Both the forward and reverse reactions continue to occur.
B. The concentration of the products is equal to the concentration of the reactants.
C. The reactants are completely used up.
D. The concentration of the products is not equal to the concentration of the reactants.

Answer 8

B

Answer 9

You're 100% sure?

Answer 10

A.

Answer 11

What happens when the Gibbs free energy associated with an equilibrium reaction is negative?

A. Both the forward reaction and the reverse reaction are spontaneous.
B. The forward reaction is nonspontaneous and the reverse reaction is spontaneous.
C. The forward reaction is spontaneous and the reverse reaction is nonspontaneous.
D. Both the forward reaction and the reverse reaction are nonspontaneous.

Answer 12

@rvc, the trick was that they wanted you to consider when changes like pressure, temperature and concentration of substances is involved. As this happens, the system shifts as to oppose such changes, but at the mean time, they are not always equal. That is why is more general to say that the reactions continue to occur.

Answer 13

C?

Answer 14

You think C. The forward reaction is spontaneous and the reverse reaction is non spontaneous?

Answer 15

Haha, the way you asked is as if my answer is wrong.
Hehe, that is what I believe.
For me, otherwise is the other way round, because I confiund that at times.

Answer 16

Sorry! I didn't mean for it to be taken that way! I just wanted to make sure you were saying C to this question! :)

Answer 17

What does the rate of a reaction determine?

A. The amount of reactants
B. The amount of products
C. The equilibrium of the reaction
D. The speed of the reaction

Answer 18

Haha, the way you asked is as if my answer is wrong.
Hehe, that is what I believe.
For me, otherwise is the other way round, because I confiund that at times.

Answer 19

No need to apologize.
I am definetely going for C.

Answer 20

Was I correct for the previous question?

Answer 21

Rate means something over time.
It will be equilibrium.

Answer 22

hey
net problem here :)
sorry
whats going on?
