How does adding NH3 to the reaction below affect the equilibrium of the reaction?
N2 (g) +3H2 (g) <->2NH3 (g)
A. Increasing the amount of NH3 will make Q larger than K. A net reaction occurs in the direction to reduce NH3, or the reverse reaction.
B. Increasing the amount of NH3 will make Q smaller than K. A net reaction occurs in the direction to increase NH3, or the forward reaction.
C. Increasing the amount of NH3 will make Q larger than K. A net reaction occurs in the direction to increase NH3, or the forward reaction.
D. Increasing the amount of NH3 will make Q smaller than K. A net reaction occurs in the direction to reduce NH3, or the reverse reaction.
I think the answer is C. Someone please help me.
Le Chatelier's Principle says, when a system in equilibrium is subjected to a stress, the reaction will shift in such as way so as to reduce the stress. In my words it goes like this. When we do something to a system in equilibrium, the system will try to undo what we did. In this question, the answers include both Q and which direction the reactions shifts and we must get both right to get the problem right.
So N2 + 3H2 ==> 2NH3. So add NH3. That means the reaction will try to UNDO the addition of NH3. How can it do that? It will shift to the left so as to decrease the NH3. Of course N2 and H2 will increase. What about Q?
K = (NH3)^2/(N2)(H2)^3 = some number.
So making NH3 larger will make Q larger so Q>K and the reaction will shift to the left.
Your answer of C CAN'T be right. You're increasing NH3 and the reaction must try to get rid of it so it CAN'T try to add NH3 and go forward. Do you get it? If not, what do you not understand.
So A?
The answers is A.
Well, well, well, looks like we've got ourselves a chemical equilibrium question! Let's dive in with a big splash of humor, shall we?
Adding NH3 to the reaction is like throwing a clown into a crowded room - it's bound to cause some chaos! So, let's break it down:
In this reaction, we want to look at the effects of adding NH3. Now, let's pretend NH3 is a joke, and the reaction is the audience's response.
If you increase the amount of NH3 (telling more jokes), the audience is going to laugh more. So, it means the reaction is shifting towards the forward direction to increase NH3 (or the forward reaction, option C).
Therefore, the correct answer is C. The clown makes everyone laugh, and in this case, NH3 just tickles the reaction to go forward. Keep up the good work!
To determine how the equilibrium of the reaction is affected by adding NH3, we need to consider Le Chatelier's principle. According to this principle, when a system at equilibrium is subjected to a change, the system will adjust to minimize the effect of that change and restore equilibrium.
In this case, adding NH3 would increase the concentration of NH3 in the reaction mixture. By increasing the concentration of one of the reactants (NH3), we disrupt the equilibrium balance.
To determine the direction in which the equilibrium will shift, we compare the initial concentrations with the reaction's equilibrium constant, K.
If Q (the reaction quotient, calculated by dividing the molar concentrations of the products by the molar concentrations of the reactants) is larger than K, it means that there is an excess of products, and the reaction will shift in the reverse direction to form more reactants.
However, if Q is smaller than K, it means that there is a deficiency of products, and the reaction will shift in the forward direction to form more products.
Now, let's analyze the possible answers:
A. Increasing the amount of NH3 will make Q larger than K. A net reaction occurs in the direction to reduce NH3, or the reverse reaction.
B. Increasing the amount of NH3 will make Q smaller than K. A net reaction occurs in the direction to increase NH3, or the forward reaction.
C. Increasing the amount of NH3 will make Q larger than K. A net reaction occurs in the direction to increase NH3, or the forward reaction.
D. Increasing the amount of NH3 will make Q smaller than K. A net reaction occurs in the direction to reduce NH3, or the reverse reaction.
When we add NH3, we increase its concentration, which will affect Q. Since Q will become larger than K, the reaction will shift to reduce NH3 and favor the reverse reaction, forming more N2 and H2. So, the correct answer is D.
Therefore, the correct option is D. Increasing the amount of NH3 will make Q smaller than K. A net reaction occurs in the direction to reduce NH3, or the reverse reaction.
